CONVERGE can model both CFD and solid heat transfer in the same simulation, making it straightforward to predict the temperatures in solids that are dependent on fluid interfaces, e.g., heads and valves in engines. This course will discuss conjugate heat transfer modeling in CONVERGE, including time control methods such as super-cycling, which accounts for disparate timescales in the solid and fluid domains by allowing the solid side of the simulation to progress with faster timescales than on the fluid side of the simulation. We will also discuss valve/seat contact resistance in engines, which is critical to accurate prediction of valve and head temperatures.
