Ground and microgravity results of a circumferentially microgrooved capillary evaporator

Flat heat pipes for potential application in fuel cell cooling

“…Microgroove has demonstrated to be reliable to work under ground and microgravity applications as reported by Bazzo et al [13], where results of CPLs with a circumferentially microgrooved capillary evaporator were presented using water, ammonia, acetone and freon 11 as working fluids.…”

“…The simulation was performed starting with a low power input, using the Engineering Equation Solver (EES) software, making use of the boundary conditions (6), (13), (14) and (15). Equation (12) is iteratively solved for the n control volumes as shown in Fig.…”
