Summary

THE FINITE-DIFFERENCE FORM OF THE BASIC CONSERVATION EQUATIONS IN LAMINAR FILM BOILING HAVE BEEN SOLVED BY THE FALSE-TRANSIENT METHOD. CENTRAL DIFFERENCING IS USED FOR DIFFUSION TERMS, UPWIND DIFFERENCING FOR CONVECTION TERMS, AND EXPLICIT DIFFERENCING FOR TRANSIENT TERMS. SINCE AN EXPLICIT METHOD IS USED THE TIME STEP USED IN THE FALSE-TRANSIENT METHOD IS CONSTRAINED BY NUMERICAL INSTABILITY. IN THE PRESENT PROBLEM THE LIMITS ON THE TIME STEP ARE IMPOSED BY CONDITIONS IN THE VAPOUR REGION.
