Lateral Edge Effects on the Sherwood Number in Turbulent Flow Over a Flat Plate
Journal of Heat Transfer, 2017Experimental results for the Sherwood number variation near the lateral edge of the active surface of a smooth, finite-width flat plate in turbulent boundary layer flow are presented. Using naphthalene sublimation, local mass transfer rates are found for two different free stream velocities.

On the relationship between Aris and Sherwood numbers and friction and effectiveness factors
Chemical Engineering Science, 2008Abstract We present a general solution of the diffusion–reaction problem for linear kinetics and an expression for the effectiveness factor ( η ) in terms of the shape normalized Thiele modulus ( Φ ) for a catalyst particle of arbitrary shape and with an arbitrary activity profile.

AbstractAn expression for Sherwood number is developed from first principles for combined pressure‐driven and electroosmotic flow in a porous rectangular microchannel. This quantifies the mass transfer of an electrically neutral solute in the microchannel and is useful for designing microfluidic devices and porous media flows.

The effect of Peclet on the Sherwood number in high porosity granular media
2002The Sherwood number representing the mass transfer coefficient for transport from a moving fluid to a swarm of spherical particles is calculated in the range of high porosities. The mass transport problem is solved both analytically and numerically under the assumption of instantaneous adsorption upon the liquid-solid interface. The velocity components

Abstract A freely moving, machined sphere of graphite (or a rounded particle of a coal char) attached to a very thin, flexible thermocouple has been burnt in a bed of silica sand fluidized by air. Simultaneous measurements were made of [CO] and [CO2] in the off-gases, as well as of the temperature of the burning particle.

Mass transfer and terminal velocity of toluene drops rising in an extraction column was studied experimentally. The impact of packing was investigated by inserting a structured packing in three different heights of 10, 25 and 40 cm inside the column.

Abstract Triphase catalysis (TPC) has the potential for conducting phase-transfer catalyzed reactions in the continuous mode. However, there is so far no industrial acceptance of this possibility since the reaction rates achieved are usually low due to diffusional limitations.

Apparent particle Sherwood numbers in the fluidized bed combustion of biomass and coal chars
1998Combustion of chars from a biomass fuel and from a bituminous coal has been carried out in a laboratory scale fluidized bed reactor with the aim of evaluating apparent particle Sherwood numbers. Comparison of the carbon conversion rate of the biomass with that of the bituminous coal indicated that extensive attrition of the biomass char particles and ...
