Authors: Dehdashti, Esmaeil; Masoud, Hassan
We theoretically study forced convection heat transfer from a single particle in uniform laminar flows. Asymptotic limits of small and large Peclet numbers Pe are considered. For Pe << 1 (diffusion-dominated regime) and a constant heat flux boundary condition on the surface of the particle, we derive a closed-form expression for the heat transfer coefficient that is valid for arbitrary particle shapes and Reynolds numbers, as long as the flow is incompressible. Remarkably, our formula for the average Nusselt number Nu has an identical form to the one obtained by Brenner for a uniform temperature boundary condition (Chem. Eng. Sci., vol. 18, 1963, pp. 109-122). We also present a framework for calculating the average Nu of axisymmetric and two-dimensional (2D) objects with a constant heat flux surface condition in the limits of Pe >> 1 and small or moderate Reynolds numbers. Specific results are presented for the heat transfer from spheroidal particles in Stokes flow.

In organizational behavior, the workforces' innovative behavior is a widely researched issue due to its meaningful relationship with various organizational outcomes. In the same way, effective behavior is an outcome of various dynamic issues among which the leadership behavior is worth mentioning. The leaders, over the intellectual stimulation, motivate and inspire their workforces to show their efforts and potentials by adapting innovative ways to achieve organizational objectives. The concerned workforces might be able to realize the said objective more effectively when they have justifiable insight about the provision of fair rewards. In this connection, this article aimed at exploring relationships among variables understudy in the context of higher educational institutions, KP, Pakistan. Applying the statistical procedures, this study provides significant evidence about the relationships among research variables which might be helpful for the institutional management in introducing suitable policies, programs, and practices for promoting the workforces' innovative behavior in higher institutions.
