The Exhaust Manifold is a pipe that collects exhaust gases from many cylinders into a single pipe. The term “manifold” comes from the Old English word manigfeald, which means “folding together multiple inputs and outputs”. The exhaust manifold is a crucial part of an engine’s system because it keeps the engine’s performance and efficiency high.
To analyze the working process of an exhaust manifold, it is necessary to consider its thermal characteristics. The exhaust manifold’s heat transfer coefficients depend on the temperature and pressure. Therefore, a model that considers the temperature and pressure conditions inside the manifold is required to accurately analyze its thermal characteristics.
