Abstract

Melting a miscible substrate by a heated overlying pool of higher density is studied experimentally. The heated pool is either carbon tetrachloride or diiodomethane, and the substrate is frozen benzene. By performing the experiments with heated pools of different densities the effects of pool-to-substrate temperature differences and pool-density to melt-density ratios on melting heat transfer are independently studied. Heat transfer rates are reported as a function of both temperature difference and density ratio. A model is postulated and compared with experimental results. The downward heat flux is found to be essentially independent of temperature differences, while being an increasing function of the density ratio between the pool and the melting solid for large density rations. For low-density ratios a buoyant plume analysis was used to obtain a correlation.
