For all other petrochem 5th sem syllabus for diploma m scheme tndte you can visit Petrochem 5th Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for heat transfer is as follows.
Rationale:
Most of the chemical engineering operations will involve either heat addition or heat removal in one way or the other. It is, therefore, extremely necessary to have good understanding about the heat transfer mechanisms such as conduction, convection and radiation. This subject enables the students to apply the understanding of heat transfer mechanisms such as conduction, convection and radiation for understanding the performances of various heat transfer equipment such as heat exchangers, condensers, boilers, evaporators etc. used in almost all chemical and related industries. The knowledge of this subject helps in design and fabricate different heat exchange equipment.
Objectives:
On completion of the units of syllabus the students must be able to know about
- Mechanism of Heat Transfer, and Heat Transfer by conduction;
- Conduction through Composite walls and Hollow cylinders
- variation of Thermal conductivity with temperature.
- To calculate the amount of heat loss through flat wall and cylinder.
- To study the concept of convection heat transfer dimensionless numbers
- To calculate the amount of radiation and the laws.
- Principles of Heat Transfer in Fluids, Log Mean Temperature Difference
- Heat Exchange Equipment (Double Pipe, Shell and Tube, Plate Type, Fin).
- To study the construction, working and application of various types of heat transfer equipments.
- Principle of Evaporation, Performance of Evaporators, Types of Evaporators and their operational methods
- Evaporator accessories
- Multiple effect evaporators and methods of feeding
- To study some of the evaporator accessories.
- Insulating materials, need for insulation, properties and their applications.
