Empirical formulaExposureIndoor air qualitySorptionImpact of airborne particles on convective mass transfer coefficient (hm) of semivolatile organic compounds (SVOCs) at flat surfaces has been investigated by assuming gas-particle equilibrium partition. In realistic indoor environments, however, this ...
We derive a formula that expresses the reaction kinetics in terms of the mass transfer coefficient. A moderately transport-limited kinetics is not readily recognizable from the shape of the binding curve and may lead to erroneous estimates of the rate coefficients. We apply our results to ...
The velocity profile in a laminar boundary layer changes complicatedly by the ratio of axial velocity to rotating one, but it was expressed by a single formula. On the other hand, the temperature profile was assumed by cubic polynomial. The step function factor was numerically obtained by HI...
differential equations and obtain the competence of the convective longitudinal fin having variable thermal conductivity14. To optimize the structure and mass of a fin, the variational calculus approach has been used15. The decomposition technique was used to estimate the ideal length and affectiveness ...
The result shows that in the first-order approximation the Nusselt number of heat transfer in a curved pipe does not differ for uniform wall temperature or uniform heat flux case, in both laminar and turbulent regions. In the latter part, the formulae of Nusselt numbers obtained by the ...
A simple approximate formula is suggested allowing determination of the mean Sherwood number with adequate accuracy. A chain of reacting particles is considered and a qualitative analysis of mass transfer for the chain of spheres is performed. It is shown that interaction of the diffusion wakes and...
