Experimental and computational investigation of single particle behavior in low Reynolds number linear shear flows

Trajectories of a buoyant spherical solid particle in a linear shear flow were investigated at low Reynolds numbers. A two-dimensional CFD analysis was performed to simulate the solid-fluid flows. Our numerical model, the discrete phase element method, was used to model and simulate the fluid domain and particle motion as the solid phase. The reliability of the computational results was evaluated for the particle trajectory. The agreement between the numerical results with the experimental data was quantified.

On the form of the power equation for modeling solar chimney power plant systems

Recently several mathematical models of a solar chimney power plant were derived, studied for a variety of boundary conditions, and compared against CFD calculations. The importance of these analyses is about the accuracy of the derived pressure drop and output power equation for solar chimney power plant systems (SCPPS). We examine the assumptions underlying the derivation and present reasons to believe that some of the derived equations, specifically the power equation in this model, may require a correction to be applicable in more realistic conditions. The analytical resutls are compared against the available experimental data from the Manzanares power plant.
