UNIBG is involved in the WP 8 and 9.
A collaboration with TUE is defined in order to obtain physical models from the FEM analysis for the lumped capacitance simulation of a propylene by-pass valveThe construction of the thermal chamber in China is delayed and at the present conditions is likely that the comparison of the ground model simulation with experiments (i.e. the WP 8.3) will not be carried outW

OBTAINED RESULTS
A Loop Heat Pipe model was built with the following mesh characteristics:
The pipe is divided in The pipe is diviTh15 in the vapour line (1 temperature-varying capacitances), 13 in the liquid line (1) and 65 in the condenser line (1). The radiator is divided in 176 thermal nodes having temperature-varying capacitances. The evaporator is constituted by 5 capacitance nodes. The fluid line has capfluid nodesffluid nodes. The evaporator 3 (reservoir, wick & grooves).
