WEBINAR ON DEMAND Learn to perform conjugate heat transfer simulations with CFD and explore the capabilities of HELYX. Multiple modes of physics including convection, diffusion, radiation, heat transfer resistance, and heat generation must be captured accurately by a conjugate physics model.  Fast, accurate, and stable conjugate heat transfer simulation is crucial for the CFD engineer […]

Simulating Conjugate Heat Transfer in CFD

In thermal simulations, most real world cases involve the transfer of heat between different states of matter, such as from solid to liquid. This is known as Conjugate Heat Transfer (CHT). Understanding the complex thermal interactions between these states allows us to enhance the thermal performance of electronics, engines, heat exchangers and much more.  However, […]

Simulating the “Porpoising” Phenomenon Using HELYX

Amongst the most significant changes that the 2022 FIA regulations brought to Formula 1 are those directly related to the aerodynamic design of the car. With attention focused on the revolutionary 3D-contoured underfloor, the teams now heavily rely on its efficient design to produce the majority of the car’s total downforce. This new tunnel-style underfloor, […]

Fan Noise Simulation Using HELYX

Automotive cooling fans are one of the major noise sources within a vehicle and can generate 85dBA at certain frequencies. That’s as loud as a lawn mower or a screaming child. Extended periods above 85dBA can lead to permanent hearing loss. With the average American spending 8.5 hours driving per week, reducing fan noise is […]

Power in Numbers: Assessing Vehicle Convoy Aerodynamics with CFD Simulation

instantaneous velocity at wheel hub height

While the idea of autonomous driving has been around for many decades, recent advances in software, computational power, sensors and mobile communication techniques have accelerated the development and understanding. Already, drive assistance systems, such as lane holding, cruise control and emergency braking have made it into production cars, making a ride in a vehicle more […]

Introduction to Meshing with HELYX

Creating a computational mesh is an extremely important step in the overall process of CFD analysis. A “bad” mesh leads to solver instability; poor resolution of important flow features; poor parallel performance of your solver; and in general, inadequate and inefficient use of CFD as a design tool. A “great” mesh enables your CFD solvers […]
