### Heat Transfer (MATH-430)(BS-VIII)(Regular & Self Support)

Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, & exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conductionthermal convectionthermal radiation, & transfer of energy by phase changes. The objectives of heat transfer include the following: Insulation, wherein across a finite temperature difference between the system & its surrounding, the engineer seeks to reduce the heat transfer as much as possible. The learning outcomes of this course are: to explain the basics of heat transfer, to explain the importance of heat transfer, to define the concept of boiling & condensation, to define the concept of heat exchangers, to explain heat transfer by conduction, to explain the Fourier heat conduction law, to define thermal conductivity coefficient & diffusion coefficient, to explain heat  transfer with convection, to explain Newton’s law, to explain free transport phenomenon, to explain the forced convection, to explain heat transfer by radiation.

Pre-Requisites:

Thermodynamics-I

Intended Learning Outcomes

On successful completion of this course students will be able to:

1. Understands the basic principles of conduction, radiation, and convection heat transfer.
2. Extend the basic principle of conservation of energy to systems that involve conduction, radiation, and heat transfer.
3. Train students to identify, formulate, and solve engineering problems involving conduction heat transfer.
4. Train students to identify, formulate, and solve engineering problems involving radiation heat transfer among black surfaces and among diffuse gray surfaces.
5. Train students to identify, formulate, and solve engineering problems involving forced convection heat transfer, natural convection heat transfer, and heat exchangers.
