Heat transfer of intake port for hydrogen fueled port injection engine: A steady state approach

The steady state heat transfer analysis of intake port for hydrogen fueled port injection engine is investigated. One dimensional gas dynamics was described by the flow and heat transfer in the components of the engine model. The engine model is simulated with variable engine speed and equivalence r...

One dimensional gas dynamics was described by the flow and heat transfer in the components of the engine model. The engine model is simulated with variable engine speed and equivalence ratio (φ).
