I am a student of aerospace engineering and much more interested in the thermal analysis
I need online sources for thermal analysis and design. please help me in finding some good sourses
Even thermal analysis is a broad topic.
Heat transfer is involved in many types of energy/propulsion systems.
Starting at the low end, spacecraft (in the vicinity of sun/star, electronic components and astronauts need to be cooled.)
For energy systems, one could choose a number of thermodynamic cycles (e.g. Rankine, Brayton, or Stirling). On a planet, one could reject heat into the ground, or atmosphere, or radiate it to space.
Heat pipes are one method of heat transfer.
Here are some examples and thermal analysis systems -

General thermal analysis software is commercially available, otherwise one must write one's own code based on the numerical solution of relevant partial differential equations related to heat transfer.
