Experimental analysis and modeling of transient dissolution of RDX through mass transfer processes
… was evaluated by correlating k to the modified Sherwood number. The modified Sherwood number was fitted with a least-squares method that approximated non-aqueous phase liquid (NAPL) dissolution [Miller et. al., 1990]. This study adjusted the constants developed with the obtained modified …

A study of the influence of physical parameters on the drying of porous media
… for the drying time is developed through use of Sherwood number, Reynolds number, and Schmidt number. This is achieved by using the non-dimensional quantities and acquiring a linear regression and equation. The coefficients and exponent values of the general equation for the Sherwood number are …

The Investigation of Aspects of Chemical Looping Combustion in Fluidised Beds
… combustion are discussed, including 1) the Sherwood number in the fluidised bed; 2) properties of different oxygen carriers, Fe2O3 and CuO (with supporting materials), were tested in the fluidised bed reactor; 3) the simulation of a steady state and a dynamic model of a coal-fired CLC power …

Mass transfer from spherical gas bubbles and liquid droplets moving through power-law fluids in the laminar flow regime
… The Nakano and Tien stream functions allow the Sherwood number to be determined as a function of the Peclet number, power-law index, and a viscosity ratio parameter. The Hirose and Moo-Young relation is shown to be a limiting case of this solution. Mass transfer rates increase as the fluids …

Heat and Mass Transfer Performance and Flow Characteristics of an Offset -Strip Array at Reynolds Numbers Up to 100,000
… vortices are being shed. The associated Strouhal numbers are approximately 0.15 and 0.20. The PIV experiments reveal the flow to be in a turbulent, vortex shedding regime. The friction factor, Sherwood number, and Nusselt number are determined by experiment to be approximately twice that predicted …

Sensitivity analysis on steady bionanofluid boundary layer flow
… among the independent variables, local Sherwood number is most sensitive to the Lewis number whereas the bioconvection Péclet and Schmidt numbers are the key drive parameters to the local density of motile microorganism. The theoretical study that comes with numerical results serve as an …

Influence of Purge Flow Swirl and Passage Discrete Hole Injection Angle on Turbine Blade Endwall Cooling
… blades. Detailed measurements for the endwall Sherwood number and film cooling effectiveness are made over a range of blowing rates, purge flow swirl angles, and discrete hole injection angles. The work is split into four complementary experimental cases. In the first case, a 45° straight …

Combustion of Coal in Shallow Fluidised Beds
… affects both the burning rate and particle/gas Sherwood number. The burning rate of carbon has been measured experimentally at a number of operating conditions and these results are compared with predicted values. The presence of burning coal particles is found to increase the heat transfer rate …
