✦ Synopsis

In this paper we study the heat transfer from the bottom of a flume to the viscous fluid flowing in it. In particular, we examine the effect of surface waves on the thermal streaks, the temperature field and the heat transfer of the bottom of the flume, under natural and forced convection. It is shown that, under natural convection conditions, there is a considerable effect of the surface waves on the thermal structure in the near-wall region. In a developed turbulent flow this effect is rather small.

## Abstract Effect of fins on heat transfer around a tube was investigated experimentally. A test tube of 30 mm diameter was installed in a test section of an open‐type wind tunnel as a single tube, or as a center tube in a single tube row and in a tube bundle of staggered layout.

Experimental investigations have been carried out for combined convective flows of air induced around uniformly heated, horizontal cylinders. Three cases of aiding, opposing, and cross flows were examined. The experiments covered the ranges of the Reynolds and modified Rayleigh numbers of Re d = 50
