A Perturbation Analysis of the Fully Developed Convective Heat Transfer inside a Longitudinal Corrugation Channel
A theoretical research of the flow and heat transfer inside two longitudinally corrugated tube is carried out. An approximate model is presented by applying perturbation expanding to the governing flow and energy equations. Obtaining the solutions, effects of the amplitude and number of the wave surface of the corrugated wall on the flow and heat transfer are discussed.
