Type of article: Article

Summary

DUE TO THE < LUBRICATION EFFECT > OF THE LAMINAR VAPOUR FLOW AROUND THE HOT PARTICLE THE LIQUID FLOW IS SLIGHTLY PERTURBED FROM THE FRICTIONLESS FLOW. THIS PERTURBATION DEPENDS UPON SURFACE, FREE-STREAM AND SATURATION TEMPERATURES. AN ATTEMPT HAS BEEN MADE TO INCLUDE THE INFLUENCE OF THE SYSTEM PRESSURE ON THE PHENOMENON -SO THE PRESENTED MODEL CAN BE UTILIZED IN THE DESCRIPTION OF THE COARSE PREMIXING PHASE DURING VAPOUR (THERMAL) EXPLOSION. THE APPLICABILITY OF THE MODEL TO THE CALCULATION OF VAPOUR LAYER THICKNESS IN THE STAGNATION POINT OF THE SPHERE AND ALSO OF HEAT FLUXES AT THE INTERFACE AND AT THE HOT SURFACE IS SHOWN.
