So far, I can understand the natural convection of a solid very easily, just give some heat (or flux) to a part (or the whole) solid and run the simulation. Besides this, we can control the ambient temperature and heat transfer coefficient. All good!nConsider a change in the situation, let's have an annular cylinder that is liquid-cooled by running water through the hollow cavity and we need temperature distribution of the cylinder in this situation. I tried to simulate this, clicked the Solid Thermal option, established the heat per unit volume over the annular cylindrical material. Now, if I just put a Boundary Condition of Convection at the inner surface, it is basically equivalent to establishing natural convection. It doesn't offer me an option to modify convection fluid's velocity or mass rate but just the convective heat transfer coefficient (so I have to know this beforehand-another thing that worries me). If my words seem confusing, check this video out:
https://youtu.be/61Lgly-KSYkHe is cooling the casting mold with water but to have the liquid cooling effect, all he did was to add a new convection and enter the coefficient. My itch is that how do I inculcate the extra detail of a liquid flowing with some velocity through the path in my model? This is certainly different than just natural convection.nAnother video: Here at 19:21
https://youtu.be/wbehj69Jqsc?list=LL&t=1161) the guy generates a simulation for forced convective cooling inside an electronic enclosure. He claims an inlet velocity and an outlet pressure and gets a forced airflow. Cool! My itch is that how do I get the temperature distribution of the heat sink while the air is flowing through it?nPlease let me know if you suspect some ambiguity in my question, though I have tried my best.nI am using ANSYS Discovery Live 2021 R1.n
