Dimensional reduction of hull shape using principal component analysis in CAESES.

Introducing the dimensional reduction function based on the drag optimization of KCS ships!

To optimize the hydrodynamic performance of the hull using the parametric modeling and optimization software CAESES, we first extract design variables related to the deformation of the hull's variable geometry. By increasing the number of design variables in this process, we can obtain a wider variety of deformation shapes, which in turn increases the likelihood of achieving better hull design proposals. However, the number of computational cases required for simulations (such as CFD analysis) increases exponentially (recommended number of cases S = 2^N, where N is the number of design variables), leading to significantly larger computational and time costs. To address this issue, CAESES5 offers a dimensionality reduction feature based on Principal Component Analysis (PCA) methods. *For more detailed information, please refer to the related links.

Optimization of catalytic converter performance using CAESES.

Optimization of the duct of the catalytic converter using CAESES!

Designing engine components for automobiles often involves considering many constraints, making it a challenging task within development design work. One example is the duct located just before the catalytic converter. Due to space constraints, this component is often designed to be bent quite sharply, which makes it difficult to ensure that the flow distribution is sufficiently uniform. In other words, if the flow characteristics of the catalytic converter are poor, there is a possibility that performance will decrease and emissions will increase. In this case, optimization of the duct for the catalytic converter will be performed using CAESES. *For more details, please refer to the related links.

Optimization of the shape of the volute and diffuser of a centrifugal compressor.

For shape creation, we use CAESES, and for mesh model creation and CFD analysis, we use products from NUMECA!

At the Technical University of Darmstadt in Germany (Institute of Gas Turbines and Aerospace Propulsion), research was conducted on the automatic optimization of the volute of centrifugal compressors and vane diffusers. This project was carried out in collaboration with NUMECA, a German company, and Kompressorenbau Bannewitz GmbH (KBB), a turbo machinery manufacturer. CAESES was used for shape creation, while NUMECA's products were utilized for mesh model creation and CFD analysis. In CAESES, a parametric model was created that allowed for variations in the cross-sectional shape and area distribution of the volute. For the diffuser, a non-axisymmetric design was implemented, enabling quick shape transformations by varying the misalignment angle, blade twist, chord length, pitch, and rotation through a parametric model. *For more detailed information, please refer to the related links.

Torque converter shape optimization

CAESES provides beneficial results across various fields, regardless of the products in question!

A torque converter for automobiles is a type of fluid coupling used in vehicles equipped with automatic transmissions to transmit rotational force from the engine to the drive shaft. Designers of torque converters work to minimize cavitation within the device and ensure good flow behavior of the transmission oil, aiming to maximize efficiency and torque ratio at high speeds. CAESES enables the modeling of such complex shapes and can build an optimization system that incorporates shape data into analysis software. By connecting CFD analysis software and proprietary CFD codes to CAESES, it analyzes flow behavior for each designed shape during optimization calculations and provides users with the optimal shape based on constraints. *For more detailed information, please refer to the related links.

Design and optimization of valves

The procedure explored using CAESES achieved a reduction in working time from several months to several days!

The optimization of valve design is one of many optimization targets, and by appropriately automating the design change process using CAESES and analyzing the number of implementation cases generated by the CFD solver, it is possible to significantly shorten the time to commercialization while exploring truly suitable designs under constraints. A valve is a device that opens, closes, or partially obstructs various passages to control, direct, or adjust the flow of fluid. In an open valve, fluid flows from high pressure to low pressure. Typically, the main objective of valve optimization is to adjust the flow rate passing through the valve at a specified pressure loss. This is often expressed as a flow coefficient, which serves as a relative measure of flow efficiency. *For more detailed information, please refer to the related links.

Optimization of the poppet valve

This article explains the design system based on the collaboration between the CFD solver SimericsMP and CAESES, based on actual research conducted!

The Italian company OMIQ SRL, which sells software, conducted research on an automatic design system using the poppet valve of high-pressure pumps developed by the Danish machinery manufacturer Danfoss. In this case, we will introduce the design system that integrates the CFD solver SimericsMP with CAESES based on the research that was actually conducted. The issue in this case is that the poppet valve exhibits unacceptable unstable behavior during operation. It was found that when the poppet valve attempts to open to its maximum displacement (27.5 mm), the instability of the flow increases, resulting in a decrease in pressure on the poppet valve, ultimately preventing the valve from fully opening (closing to about 6 mm remaining). This unstable phenomenon was verified through unsteady analysis using SimericsMP. *For more detailed information, please refer to the related link.

Optimization of the air intake for AIPOD.

Introduction to parametric modeling using CAD and optimization software CAESES.

This article introduces the air intake optimization of ramjet engines using AIPOD, our self-developed optimization platform. Ramjet engines are designed for air intake at Mach numbers of 3 and above, where the mixture flows in and the exit becomes subsonic, making it a type of jet engine. To accommodate different flight Mach numbers, a center cone called a spike can be moved forward and backward, and when the maximum flight Mach number of 3.5 is reached, the Mach line formed at the tapered vertex intersects exactly with the lip. *For more detailed information, please refer to the related links. For further details, you can download the PDF or feel free to contact us.

Optimization of the Leading Edge for Boundary Layer Experiments on a Flat Plate

When the minimum curvature radius is approximately 2.5mm, it is possible to prevent plastic deformation of the steel belt!

Predicting transitional boundary layers under arbitrary conditions in fluid mechanics is a very challenging task. A research group at Karlsruhe Institute of Technology conducted tests for predicting transitional boundary layers considering the effects of pressure gradients, mainstream turbulence, and surface roughness, using CAESES and the open-source OpenFOAM for suitable leading-edge shape optimization. *For more details, you can view the related links.
