Abstract

The pressure recovery in a cylindrical, organic heat pipe has been measured at average radial Reynolds numbers, Re-r, between 5 and 150 and from small to high vapour velocities up to an average Mach number of one. At maximum local Mach numbers below 1 the pressure recovery depends essentially only on Re-r. It increases with Re-r, reaches a value of 93 to 94 % at Re-r about 50 and remains then constant. If the local Mach numbers reach or exceed 1 a strong decrease of the pressure recovery occurs independent of the radial Reynolds number.
