Automotive

In the automotive sector, optimizing the product design and development process is crucial to reducing costs and time for the final product due to the dynamic environment and frequent design changes. Over the past few decades, the use of CFD approaches has become increasingly popular in the industry, owing to their ability to employ highly capable analytical models for fluid flow and heat transport simulations.

The dynamic environment and frequent design changes that define the automotive sector call for efficient designs to save product costs and cycle times. The usage of CFD techniques in the automobile industry has grown quickly because of their highly capable flow, heat transfer, and coupled analytical models. The use of CFD in the automotive industry extends from system-level design and optimisation (external aerodynamics, underhood thermal simulation) to component-level design and optimisation (engines, turbochargers, exhaust manifolds, and HVAC ducts). Via CFD, it is feasible to obtain crucial data that cannot be obtained using traditional tests. Modern CFD codes and post-processing technologies give engineers a magnified understanding of the flow physics, boosting their capacity to modify the design swiftly and improve the performance of the components even at the design stage.

External Aerodynamics

The design of fuel-efficient, stable, and high-speed vehicles depends heavily on the exterior aerodynamics of the vehicles. The drag and lift forces produced by aerodynamics have a significant effect on the cooling system, handling, and fuel efficiency of the vehicle. The use of CFD to forecast aerodynamic loads and related variables has increased quickly. Most manufacturers have used it as a regular tool for design review during the product development stage.

Blade Fluttering Analysis of A Rear Spoiler

Blade fluttering analysis is an important aspect of designing a rear spoiler for a vehicle. The rear spoiler is designed to improve the aerodynamics of a vehicle, which in turn improves its performance and fuel efficiency. Blade fluttering occurs when the spoiler blades are subjected to high-speed air flow, causing them to vibrate or oscillate. This can cause damage to the spoiler and reduce its effectiveness in improving aerodynamics.

To analyse blade fluttering, engineers use Computational Fluid Dynamics (CFD) software to simulate the air flow around the rear spoiler.This simulation helps identify the areas where blade fluttering may occur and how it can be minimised or eliminated.
The designed model is imported into the CFD software, which simulates the air flow around the spoiler at various speeds and angles of attack. The software can also simulate different weather conditions and road conditions to accurately predict the behavior of the spoiler in different scenarios.

The simulation results are analyzed to identify any areas where blade fluttering may occur. Engineers then adjust the design of the spoiler to reduce or eliminate these areas. This may involve changing the shape or size of the spoiler, adjusting the angle of the blades, or adding reinforcements to the blades to prevent them from vibrating.
