PARAMETRIC STUDY OF THE PRESSURE CHARACTERISTIC CURVE IN A BOILING CHANNEL
SINOPSIS
The main objective of this work is to understand the behavior of the pressure drop of a boiling fluid along a heated pipe as a function of the mass flux. The steady-state plot of the pressure drop against the mass flux of a heated boiling channel with subcooled liquid at the inlet is widely used for pressure drop and thermal oscillations simulations. The influence of several important parameters, such as the heat applied, the inlet pressure, and the inlet temperature, is analyzed. As the inlet pressure goes down, the steepness of the negative slope of the static curve increases. The inlet temperature has a very important role in this plot, showing that the negative slope of the curve gets steeper as the subcooling increases. Although the amount of heat applied to the test section is found to have no influence on the shape of the static curve, the axial distribution of the heat along the heated section plays a very important role in the steepness of the negative slope of the steady-state pressure drop versus mass flux plot.
