An apparatus implementing this technique was fabricated. The characteristic parameters of the apparatus are as follows: the heating pulse length, 1 to 10 ms; the heat flux density through the surface of a 20 µm probe, 1 to 10 MW/m2; repeatability of selected power value in a series of pulses is on a level of 0.05%. As an example, the constant heating power mode is applied for comparing the thermal resistance of nanofluids in the region of stable states of liquid and superheated (with respect to the liquid-vapor equilibrium temperature of the base liquid) ones. The parameter was the content of Al2O3 nanoparticles in the base liquid (isopropanol). Доп.точки доступа: Skripov, P. V.; Скрипов Павел Владимирович
