Abstract

A theoretical and experimental investigation of a water jet impinging and freezing on a melting solid surface has been carried out. Attention was focused on the stagnation region of an axisymmetric jet. In the experiment, a water jet was directed upward against the lower end of a meltable rod having a diameter about twice that of the jet orifice. Solid octane (m. p. -56. 5 C) and solid mercury (m. p. -38. 9 C) served as the meltable materials. A laminar-stagnation-flow model was developed to describe melting heat transfer in the presence of jet solidification within the impingement region. Measurements of the melting rate and conditions for the onset of jet solidification were found to agree quite well with the values predicted with this model.
