Entrance hall air conditioning analysis

Air conditioning analysis of the entrance hall was conducted during the basic design phase.

The entrance hall targeted for analysis is a large space with a height of approximately 20 meters. During the basic design phase, it is crucial to verify whether there are any issues with the temperature distribution and airflow distribution in the living area, based on the position, number, wind speed, and temperature of the air conditioning air outlets. This is very important for considering comfort and energy efficiency. Additionally, changes in conditions due to the seasons must also be taken into account. In this analysis, we detailed the internal space shape of the building, the arrangement of air outlets and inlets, and the thermal load, conducting air conditioning analysis for summer, winter, and transitional periods.

Analysis of airflow around the cooling tower

Reproducing the thermal flow conditions around cooling towers with unknown characteristics and behaviors!

Thermal fluid equipment related to building facilities often has many unknown characteristics and behaviors. Cooling towers are one such example, but by precisely setting the structure, flow conditions, and thermal conditions of each cell of the cooling tower, it is possible to reproduce the thermal flow state quite accurately. In this analysis, we conducted a cooling tower thermal flow analysis considering external winds to examine the impact of multiple cooling towers with different specifications on the temperature distribution of the heated air released from each cell in relation to the airflow conditions around high-rise buildings.

Air Conditioning Analysis in an Electrical Components Factory

We conducted an air conditioning analysis using an electrical components factory with a clean room as an example.

The air conditioning analysis of an electrical components factory was conducted using a factory with a clean room as an example. Unlike general architecture, where aesthetics are emphasized, in facilities such as factories, functionality such as air conditioning performance and ventilation efficiency takes precedence over design. Even when achieving the same ventilation and air conditioning performance, there is often significant potential for cost reduction regarding the layout of ducts and outlets.

Inclined apartment-style environmental analysis

Examining the difficult issues of a condominium built on a slope due to changes in the wind environment.

The purpose of wind environment analysis in sloped terrain is to examine some of the difficult issues that exist within wind environment analysis. Analyzing areas that include sloped and undulating terrain is one of these issues. The reason for this is that the presence of elevation differences between buildings and their foundations makes it challenging to create analysis models. Another reason is the question of how to set the conditions for approaching wind on sloped terrain. Like in typical flat terrain analysis, a power-law distribution is generally used as a basis, but it is preferable to establish a distribution along the slope's inclination. Furthermore, there is a need to set the height of the sky plane higher than in standard analyses. For more details, please download the catalog.

Moving Boundary: Analysis of Wind Pressure Acting on a Running Train

We analyzed the aerodynamic pressure exerted by a moving train.

Moving Boundary: The analysis of wind pressure acting on a moving train was conducted using numerical simulations that take into account the moving boundary. It has been pointed out that strong winds, such as those caused by typhoons, pose a risk of overturning moving trains. Therefore, understanding the wind pressure acting on a moving train is important. For more details, please download the catalog.

Analysis of the wind environment around the apartment complex

The analysis results for a condominium building located in an urban area were conducted for summer and winter.

The analysis of the wind environment around the condominium was conducted for condominium buildings located in urban areas, focusing on the results for summer (southwest wind) and winter (north wind). When constructing or expanding buildings in urban areas, the wind conditions within the site or surrounding area can change significantly. This is known as the wind environment (building wind) issue. Generally, an investigation is conducted on the changes in wind speed distribution caused by the presence of the planned building for all wind directions (8 or 16 directions), comparing it to the conditions before construction. For a simplified evaluation, analysis is performed only for the prevailing winds of each season. For more details, please download the catalog.

Analysis of Wind Environment Around High-Rise Buildings

Investigating the changes in wind environment when high-rise buildings are constructed in areas with relatively open surroundings.

The analysis of the wind environment around high-rise buildings aims to investigate the degree of impact on the surrounding area, which inevitably increases. In urban areas, it is not uncommon for buildings over 100 meters tall to be constructed; however, in such cases, the impact on the wind environment (building wind) differs significantly compared to situations where relatively low-rise apartments are built in residential areas. For buildings exceeding 100 meters, the areas of reverse flow that appear on the approach (windward) side, as well as the wakes (downstream vortices) that occur behind, become very large, resulting in a correspondingly significant impact on the surroundings. This analysis examined the changes in the wind environment when high-rise buildings are constructed in areas where the surroundings are relatively open.

Heat flow analysis in thermal storage tank

Reproduction of ducts and structures inside the heat storage tank, thermal flow analysis related to liquid flow velocity and temperature stratification.

The thermal flow analysis within the thermal storage tank reproduces the ducts and structures inside the tank and conducts thermal flow analysis regarding the flow velocity and temperature stratification of the liquid within the tank. When predicting the performance of the thermal storage tank, it is crucial to understand the temperature distribution changes of the fluid inside the tank. This characteristic is greatly influenced by the shape and flow velocity within the tank, affecting the temperature stratification of the liquid in the thermal storage tank.

Thermal fluid analysis in continuous casting machine molds

Simulation experiment on the influence of the flow state of molten steel flowing into the mold from the immersion nozzle.

In the thermal fluid analysis of the continuous casting machine mold, we conducted a thermal fluid analysis related to the continuous casting equipment in steelmaking plants. We faithfully modeled the mold and immersion nozzle to reproduce the flow within the molten steel bath, which is extremely important for controlling the thickness of the solidification shell and reducing non-metallic inclusions, making it an essential requirement for high-speed casting equipment. In this analysis, we simulated the impact of the flow of molten steel entering the mold from the immersion nozzle, as shown in the diagram below. For more details, please download the catalog.

Moving Boundary: Flow Analysis in a Stirring Tank Due to Impeller Rotation

Visualization of the fluid behavior in the tank generated by the rotation of the impeller, accompanied by a moving boundary.

Moving Boundary: In the flow analysis of a mixing tank caused by the rotation of an impeller, we conducted a numerical simulation with moving boundaries to visualize the behavior of the fluid generated by the rotation of the impeller within the tank. The mixing and blending of fluids in a mixing tank is one of the important processes in the chemical and bio fields. There are various types of blade shapes, and the goal is to sufficiently mix and blend the contents inside the mixing tank. For more details, please download the catalog.

Analysis of airflow and heat within electronic device enclosures

Ventilation analysis was conducted using numerical simulations within the electronic device enclosure.

In the thermal airflow analysis of electronic device enclosures, we conducted ventilation analysis through numerical simulations within the enclosures. With the improvement of technology, electronic components are increasingly shrinking, making thermal issues within electronic device enclosures unavoidable. The placement of high-heat-generating components and ventilation parts such as fans can significantly affect the performance of the devices themselves. We conducted the analysis to gain insights into this. For more details, please download the catalog.
