MEASUREMENT OF FROST GROWTH AND DENSITY IN A PARALLEL PLATE GEOMETRY.

Author(s) : O'NEAL D. L., TREE D. R.

Summary

AN EXPERIMENTAL INVESTIGATION WAS UNDERTAKEN TO CHARACTERIZE THE EFFECT OF REYNOLDS NUMBER, AIR HUMIDITY, AIR TEMPERATURE, AND PLATE TEMPERATURE ON FROST GROWTH AND FROST DENSITY ON A VERTICAL PLATE IN A PARALLEL FLOW GEOMETRY. FROST GROWTH INCREASED WITH INCREASING REYNOLDS NUMBERS IF LESS THAN 15,900. ABOVE THIS REYNOLDS NUMBER IT SHOWED NO DEPENDENCE. IT WAS FOUND TO BE STRONGLY DEPENDENT ON THE HEAT EXCHANGER PLATE TEMPERATURE AND THE AIR HUMIDITY. AN EMPIRICAL CORRELATION RELATING FROST HEIGHT TO TIME, REYNOLDS NUMBER, PLATE TEMPERATURE, AND AIR HUMIDITY WAS DEVELOPED. FROST DENSITY INCREASED WITH TIME AND WITH REYNOLDS NUMBER.
