✦ Synopsis

The characteristics of melting and solidification of a binary mixture of p-C6H,Cl, and p-C6H,Br, were experimentally investigated in a horizontal cylindrical capsule. Since segregation occurs in the solidification and density stratification occurs in the melting, non-uniform concentration profiles were formed in both solid and liquid phases. These non-uniform density profiles generated several horizontal cells by free convection in the melting process, while only a few large vortices were generated for pure p-C6H,C1,. As a result of this difference of free convective motion, heat transfer performance of a binary mixture becomes smaller compared with that of pure material.

## Abstract An experimental study of heat transfer on a horizontal rotating cylinder near a flat plate was performed. The cylinder and plate were set in a cross‐flow. Temperature distribution and coefficients of local heat transfer were measured by a Mach–Zehnder interferometer. Flow visualization
