Many customers using "GT-SUITE" utilize simulations as a clue for the development of intake and exhaust systems, particularly regarding the acoustic performance of these systems. The advanced Navier-Stokes-based solver inherently resolves the pulsations of pressure waves within the simulated system. The results of these pressure wave pulsations propagate as noise through the engine's intake and exhaust ports. Both the level and characteristics (frequency components) of this propagated noise can be calculated. 【Features】 ■ Rapid and reliable creation and meshing of complex shapes ■ Modeling of complex components in a short time ■ Meshing of models in orthogonal 3D coordinates ■ Capturing 3D acoustic effects during the runtime of 1D system simulations ■ Executing the overall analysis, including meshing, in batch mode as part of the optimization process *For more details, please refer to the PDF materials or feel free to contact us.

I would like to introduce information about how CAE and CFD are beneficial to society, including interesting application examples, primarily based on articles from the information magazine "ADVANTAGE" published by ANSYS, Inc. and ANSYS Japan Co., Ltd. This time, I will present a CFD application case for Dyson's "Dyson Air Multiplier (a bladeless fan)." When I first saw this product in an electronics store and in commercials, I was truly amazed. The features of the bladeless fan "Dyson Air Multiplier" include: - Safety - The phenomenon of "buffeting," where airflow around an aircraft separates from the surface and creates vortices that vibrate the aircraft, does not occur. - Reduced noise - By forming a high-speed air layer that draws in surrounding air, it delivers a large volume of air, creating a smooth breeze like a natural zephyr.

This time, I will discuss the analysis of water purification treatment using ultraviolet sterilization devices. ANSYS Fluent is equipped with numerous radiation models, and in this case, we will simulate using the DO model and model various microorganisms with DPM (Lagrangian), which is a somewhat unique example. When I first saw this case, I thought it might not fall within the realm of CFD (fluid analysis), but depending on how it is used, there seems to be potential for increased applications. We will incorporate the total amount of ultraviolet light (UV Dose) that bacteria receive while flowing through the ultraviolet sterilization device using a UDF (User Defined Function). In the tap water we use and drink in our daily lives, ultraviolet irradiation devices are reportedly always used for sterilization (to kill chlorine-resistant bacteria such as Cryptosporidium). In other words, if we could improve the sterilization efficiency by even an average of 1% at the countless water purification plants across the country, it would create a significant impact.

I would like to introduce information that highlights how CAE and CFD are beneficial to society, including interesting application examples, primarily through articles from the information magazine "ADVANTAGE" published by ANSYS, Inc. and ANSYS Japan Co., Ltd. This time, we will present an interview article with Mr. Manabu Umeda and Mr. Shinichi Sagara from LIXIL Corporation, who are utilizing flow analysis of toilet products in the design and development of new products. There are various fluid analysis tools available, but the reason for choosing ANSYS Fluent is its ability to simulate products like toilets and bathtubs, which are composed of curved surfaces. One of the advantages of introducing simulation is "visualization." Since ceramic toilets can only be visually inspected up to the point where water accumulates, it is not possible to understand the flow path connected to the drainage side. With simulation, it is possible to confirm the internal flow on the drainage side, allowing for appropriate measures to be taken based on simulation results, rather than relying solely on the intuition and experience of designers. *For more details, please download the PDF or contact us.*

• Analysis and prediction system

To enhance tumble, we are calculating and comparing the flow field with and without a valve installed inside the intake port using 'CONVERGE'. In this case, due to the application of adaptive mesh refinement (AMR) according to the velocity gradient, the mesh in areas with significant velocity gradients, such as those passing through the valve, is automatically refined, allowing for calculations with higher accuracy. You can view the video of this case. 【Features】 ■ Calculation and comparison of the flow field with and without a valve installed inside the intake port ■ Automatic refinement of the mesh in areas with significant velocity gradients *For more details, please refer to the PDF document or feel free to contact us.
