Other AbstractBased on the heating start-up conditions of the space green thruster a self-developed apparatus for thermal storageexchange was set up.The influence of thickness,pore density and bulk density on the transient heat-exchange capacity(THC)between nickel foams and fluids was studied.The results indicated that THC of nickel foams increased with its thickness.The specific surface area was the key parameter to influence the THC under low pore density(20—70PPI),as THC increased with the pore and bulk density.The flow resistance became the significant parameter under high pore density(100PPI),as THC increase rapidly while it changes little with increase of bulk density.Moreover,a flow resistance apparatus was built up to measure and compare the flow resistance of nickel foams and catalyzer under forced convection.The results indicated that flow resistance increased with the pore and bulk densities.The flow resistance of catalyzer was higher than that of all nickel foams used in this work.Thermal storage exchange test,igniting test and mechanical property should be taken into overall consideration to determine the appropriate pore and bulk density of the foam in the view of practical application.
