Scavenging and the Exhaust Backpressure Myth

It is a widely spread myth that some back pressure on the exhaust is good, however this is the wrong conclusion of experimentation.  Back pressure on the VQ’s exhaust does not increase performance for naturally aspirated (NA) or turbo applications.  There are situations where smaller diameter pipes can outperform larger diameter pipes, but this is […]

Transient Analysis of Exhaust Headers Using Computational Fluid Dynamics In Solidworks Flow Simulation

Introduction Exhaust headers serve to optimize the pulsatile flow of exhaust gases from the internal combustion engine by means of resonance tuning to increase the air mass flow rate and thus the power of the engine.  The resonance characteristics of the quarter wave primary tubes is of highest importance. In a naturally aspirated engine, one

Optimization of Computer Hardware for Computational Fluid Dynamics In Solidworks Flow Simulation with AMD Ryzen 9 3900x and AMD Threadripper 3970x

Introduction Solidworks Flow Simulation can help save design time and prototyping costs immensely.  For Turbomachinery the conventional calculations can be used to get a general approximation, however these models typically do not consider all the characteristics of the flow and of the design, often making a very large generalization to simplify calculations based on maximum
