Course Aim: Course Objectives: This course -with the previously taught course (Heat Transfer (1) ME231)- is concerning with heat transfer as a basic science that deals with the rate of transfer of thermal energy. The objectives of this course are: 1. To cover the basic principles of heat transfer. 2. To present a wealth of real-world engineering applications to give students a feel for engineering practice. 3. To develop an intuitive understanding of the subject matter by emphasizing the physics and physical arguments. In engineering practice, an understanding of the mechanisms of heat transfer is becoming increasingly important since heat transfer plays a crucial role in the design of vehicles, power plants, refrigerators, electronic devices, buildings, and bridges, among other things. Even a chef needs to have an intuitive understanding of the heat transfer mechanism in order to cook the food “right” by adjusting the rate of heat transfer. Course Description: *Natural Convection Heat Transfer. *Thermal insulation: Selection and Design * Multidimensional Transient heat transfer problems * Numerical methods in heat conduction * Radiation Heat Transfer in enclsures * Effect of gas presence on Radiation H.T. in enclosures * Boiling and Condensation * Mass transfer by diffusion and convection * Simultaneous Heat & Mass Transfer......
