Pressure drop studies are very important in the view of single and two phase flow distribution and safety parameter like Critical Heat Flux (CHF). The pressure drop first decreases with increase in heat flux due to decrease in near wall viscosity until it reaches to some critical point between ONB (Onset of nucleate boiling) and OSV (onset of significant voids) then it increases with further increases in heat flux due to increase in void fraction and ultimately reaches to CHF. It may be noted that pressure drop fluctuation due to bubble induced turbulence in subcooled two phase flow is also important, which enhances further by increase in void fraction. The DPTs at HHFTF have high accuracies to  measure the pressure drop during heat flux tests.
