[Analysis Case] Multi-Cylinder Analysis of a Inline 4-Cylinder Engine

"CONVERGE" enables efficient parallel computing!

This is a case study of multi-cycle, multi-cylinder analysis of a 4-cylinder engine. "CONVERGE" enables efficient parallel computing, allowing for such multi-cylinder, multi-cycle calculations to be performed within realistic computation times. Additionally, it can be coupled with the automotive comprehensive simulation platform GT-SUITE, enabling calculations that combine the characteristics of one-dimensional and three-dimensional analyses, resulting in computations that are closer to real phenomena. [Features] - Efficient parallel computing is possible - Coupling analysis with GT-SUITE is possible *For more details, please refer to the PDF document or feel free to contact us.

Today's ANSYS mission is 'without prototyping' (Tokyo Electron)

We would like to introduce an interview article with Mr. Kazuo Kibi from Tokyo Electron Limited!

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. Kazuo Kibi from Tokyo Electron Limited. The company holds the top share in Japan and the third largest share in the world as a semiconductor manufacturing equipment manufacturer. As a long-time user of ANSYS Fluent, the company utilizes simulation to clarify and predict phenomena occurring within their manufacturing equipment. They leverage simulation software from upstream to downstream in the design process, but now the management has assigned them a more challenging mission of "not creating prototypes." Creating prototypes requires enormous costs and time. Therefore, if they can avoid making prototypes, there is no doubt that they can achieve significant economic and time benefits. *For more details, please download the PDF or contact us.

[Analysis Case] Steady-State Intake Flow Analysis of a Diesel Engine

The mesh control function included in "CONVERGE" is also very effective for steady-state calculations.

The mesh control function included in "CONVERGE" is very effective for steady-state calculations as well. This case predicts the swirl ratio of a diesel engine through steady-state calculations, and during the initial phase of analysis (when the flow field is still unstable), it efficiently predicts the overall flow pattern by calculating with a coarse mesh. Subsequently, the calculation progresses through a process of gradually increasing the analysis load while improving analysis accuracy using grid scaling and adaptive mesh refinement (AMR). 【Features】 ■ Calculate with a coarse mesh in the initial phase of analysis to efficiently predict the overall flow pattern. ■ Gradually increase the analysis load while improving analysis accuracy through grid scaling and adaptive mesh refinement. *For more details, please refer to the PDF materials or feel free to contact us.

[Analysis Case] Diesel Engine Cylinder Spray Combustion Analysis

In "CONVERGE," it is possible to achieve high analysis accuracy with minimal computational load.

In "CONVERGE," it is possible to achieve high analysis accuracy with minimal computational load by utilizing many mesh control features, including Adaptive Mesh Refinement (AMR). This is an example of spray combustion calculations in a sector model of a diesel engine, where the mesh near the spray is automatically refined during the injection period by the local refinement feature. Additionally, the AMR corresponding to temperature and velocity gradients automatically refines the mesh in the necessary areas to enhance computational accuracy, demonstrating the results of improved accuracy. 【Features】 ■ Achieves high analysis accuracy with minimal computational load ■ Mesh is automatically refined by the local refinement feature *For more details, please refer to the PDF document or feel free to contact us.

[Analysis Case] Direct Injection Engine In-Cylinder Spray Combustion Analysis 'CONVERGE'

Improve analysis accuracy! Automatically place high-resolution mesh in the flame zone area.

This is the result of calculations of the flow, spray, and combustion of a direct injection engine using 'CONVERGE'. It includes calculations of the formation of the air-fuel mixture due to fuel injection and evaporation, ignition by the spark plug, and flame propagation. The combustion model takes into account the combustion process at the elementary reaction level using the SAGE detailed reaction model. Furthermore, by automatically placing high-resolution meshes in the flame zone using Adaptive Mesh Refinement (AMR), the analytical accuracy of the flame propagation calculations is improved. [Features] ■ Considers combustion processes at the elementary reaction level ■ Improves the analytical accuracy of flame propagation calculations *For more details, please refer to the PDF document or feel free to contact us.

[Analysis Case] In-cylinder Flow Analysis (With and Without Tumble Control)

Calculate and compare the flow field with and without a valve in "CONVERGE".

To enhance tumble, we are calculating and comparing the flow fields with and without a valve installed inside the intake port using 'CONVERGE'. In this case, adaptive mesh refinement (AMR) is applied according to the velocity gradient, so 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 flow fields 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.
