To process this page used the WaterSteamPro function "wspTHERMCONDSTX": thermal conductivity coefficient in double-phase area [W/(m·K)] as function of temperature t [K], vapor fraction x [-].
Function uses functions wspTHERMCONDSST and wspTHERMCONDSWT which return thermal conductivity of steam and water at saturation line. The function uses following formula: THERMCONDx = (1 - X)·THERMCONDw + X·THERMCONDs, where THERMCONDs = wspTHERMCONDSST, THERMCONDw = wspTHERMCONDSWT and X - vapor fraction. The range of calculation is double-phase (water-vapor) area.
