Convective Heat Transfer
Convective Heat Transfer. Instructor: Dr. Arup Kumar Das, Department of Mechanical and Industrial Engineering, IIT Roorkee. Convection is a major mode of heat transfer when fluid is attached with the source. Processes of convection are fundamental and linked up with fluid mechanics laws and derivations of thermodynamics. Convective heat transfer has its wide horizon spreading from flow over a flat plate under constant heat flux or constant temperature boundary conditions to thermally developing or developed flow inside a duct. Moreover convection theories will widely vary depending on medium flow field which differentiates forced flow and natural gravity driven heat transfer modes. Convective heat transfer takes a major role in phase change heat transfer as well as mass transfer analogies in chemical processes. Present course targets fundamental understanding of all these facets with derivations and mathematical examples. (from nptel.ac.in)
| Lecture 02 - Balance of Total Energy |
We will evaluate term by term balance of energy from first law of thermodynamics. Next, we will appreciate dealing of body and surface forces. By subtracting mechanical energy from total energy, balance of thermal energy is shown. Internal energy and enthalpy form of thermal energy balance will be derived towards the end of this lecture.
