there is some materials which called self-regulating or self-controlling temperature materials and used in heating elements (some ceramics which called PTC). is that possible use these materials to make a complex body or wall constant temperature in the presence of water flow?
or do you know any way to apply constant temperature boundary condition on them? by the way body immersed in the fluid flow and I can't use phase changing.
Dear Mohsen,
if you can access the immersed body, you can inject water at very high velocity to maintain a constant wall temperature. Good luck.

Dear Mohsen,
You can use Thermoelectric cooling chip for applying almost constant temperature boundary condition which obeys Peltier law; otherwise if it is macro-scale heat exchanger, and you want to apply constant temperature boundary condition on side, you can make kind of shell and tube heat exchanger. There are lots of articles that you can easily go through.
Kindest regards,
