Abstract

Wet- and dry-bulb temperatures were measured for Hg-N2 and Cd-H2 systems in a high temperature psychrometer apparatus specially constructed for this purpose. The apparatus features a device termed a self-adjusting shield developed to minimize heat transfer by radiation. A correlation for the psychrometric ratio for spherical shaped wet bulbs was formulated and experimental results showed close agreement with the theoretical values calculated from the proposed correlation.
