i need good topics in thermal engineering to papper presentation

Mechanical Seminar Topics, Presentation Topics and Advanced Research Topics with PPT and abstract based on Technical Papers, educational articles and research journals for final year Mechanical and Automobile Engineering Students. Presentations are provided at the end of each article. Refrigeration is the process of removing heat from an enclosed space or from a substance and transferring it to a place where it is unobjectionable. Magnetic refrigeration, based on the magneto caloric effect (MCE), has recently received increased attention as an alternative to the well-established vapor compression refrigerators for room-temperature applications.

Heating or cooling of processes, equipment, or enclosed environments are within the purview of thermal engineering.
One or more of the following disciplines may be involved in solving a particular thermal engineering problem:
Thermodynamics
Fluid mechanics
Heat transfer
Mass transfer
Thermal engineering may be practiced by mechanical engineers and chemical engineers.
One branch of knowledge used frequently in thermal engineering is that of thermofluids.
Applications[edit]
Engineering : HVAC
Cooling of computer chips
Boiler design
Solar heating
In design of combustion engines
Thermal power plants
Commercial cooling system
