Аннотация

The interaction of solid particles with turbulent liquid in the vicinity of horizontal and vertical surfaces was studied using the rate of heat transfer as a measure of the magnitude of the interaction. Glass microspheres with mean diameters from 20 μm to 860 μm were used in concentrations less than 0.02 volume fraction solids. The pipe Reynolds number range was 20,000 ≤ NRe ≤ 90,000. A peak in the relative heat-transfer enhancement was observed for constant value of the product dpNRe11/16; consistent with a simple fluid-solid interaction model involving the microscale of the fluid turbulence.
