The heat transfer processes associated with the heating of the operating liquid and the calibration of the liquid calorimeters for measuring the energy of high-power microwave pulses are studied analytically and by numerical simulation. It is shown that convection significantly enhances heat transfer between the calibration and thermostabilization heaters and the operating liquid, hence, it helps to reduce the formation of bubbles in the volume of the operating liquid when controlling and calibrating the calorimeter. Heat transfer from tape heaters is noticeably more efficient than that from single wire ones. The results obtained are essential for the development of liquid calorimeters and the adjustment of their operating modes.
