Abstract
- Conjugate heat transfer in ducts is one of the most popular research topics due to its wide engineering applications. Most of the interest on the heat transfer problems is the two cases of the uniform wall temperature and uniform heat flux. However, the heat-transfer problems with non-uniform heating are also investigated by a few studies. The purpose of this work is to obtain a more general simple expression for any heat flux density and temperature profiles using compact thermal model which offers many advantages over the traditional approach using the heat transfer coefficient (i.e. any space distribution, not just uniform). Thus, a steady state compact thermal model is established and used to study Conjugate heat transfer through circular duct. The flow is considered to be laminar and hydrodynamically fully developed through the entire duct length. The temperature distributions of the moving fluid inside the duct at different sections have been presented for all investigated cases.The compact thermal model also used to investigate temperature distribution and the heat flux at the interface for conjugate heat transfer.
