APPLICATION OF ADSORPTION METHOD FOR DETERMINATION OF LOCAL CONVECTIVE HEAT TRANSFER RATES
摘要
The adsorption method of convective mass fluxes measurement is based on diffusion controlled adsorption of an organic dye, from a diluted water solution, to the surface of a thin, white adsorbent layer. Local mass transfer rates can be obtained from adsorption chromatograms, either by reflected light colorimetry or dye elution. This method is applied to some fluid-solid systems, as a thin, flat plate in the longitudinal flow, circular cylinder in the cross-flow, rotating and vibrating disc in the stagnant fluid. A correlation of local heat and mass transfer data was obtained for all systems investigated.
