Heat exchange in finely dispersed twophase flows
Abstract
Some problems are considered which relate to heat exchange in hightemperature twophase gassuspension flows containing low densities of micronsize solid particles. Formulas are given for calculating the convective and radiative components of heat transfer in such flows, and results are discussed for an experiment performed to investigate heat exchange in an airgraphite flow containing 10micron graphite particles. The observed intensification of heatexchange processes in such a flow as compared with a purely gaseous flow is explained in terms of solidparticle participation in radial heat transfer from the flow surface to its core.
