The difference between diffusivities [alpha] obtained from both experiments is approximately equal to 2%. Steady state moisture fluxes were measured and diffusivities in the lateral (x-y) and in the transverse (z) directions were calculated. They are said to be cost-effective alternatives to beryllium-copper and provide thermal coductivities of 80-190, thermal diffusivities of 1. |
