Abstract
An experimental study was conducted on the transient solidification of water in a rectangular inclined cavity. The dependence of the phase-change interface and of the volume of ice produced on time and on the inclination angle were determined. Characteristic temperature distributions in the cavity were obtained and compared to the predictions of a simple model that neglected the presence of buoyancy-driven flow in the system. Flow visualization in the liquid phase using the laser-sheet technique showed the presence of a bicellular structure. The ice nucleation time at the cold surface exhibited a maximum at an inclination angle of about 60°. An engineering correlation is also reported for the dependence of the volume of ice formed in the system on the inclination angle and on time.
