Kurzbeschreibung (Abstract)
The melting process around a heated horizontal circular cylinder embedded in a phase change material has been analyzed by means of numerical methods. Both heat conduction and convection have been taken into account to treat this moving boundary problem. Difficulties associated with the complex structure of the timewise changing physical domain (melt region) have been successfully overcome by applying a numerical mapping technique (body-fitted coordinates). Numerical solutions have been obtained for Rayleigh numbers up to Ra = 1.5 · 105, Stefan numbers in the range 0.005 ≦ Ste ≦ 0--08 and for Pr = 50. The results are discussed in detail and indicate that the influence of natural convection has to be considered in all cases.
