This paper examines a technique for generating an adverse pressure gradient using a setup that consists of a cylinder and a flat plate airfoil. The results show that the extent and nature of flow separation along the flat plate surface depended on the velocity ratio and location of the spinning cylinder.

Laboratory experiments and numerical simulation reveal that a submerged intruder dragged horizontally at a constant velocity within a granular medium experiences a lift force whose sign and magnitude depend on the intruder shape. Comparing the stress on a flat plate at varied inclination angle with the local surface stress on the intruders at regions with the same orientation demonstrates that ...

This study proposes the concept of the local heat loss coefficient and examines the calculation method for the average heat loss coefficient and the average absorber plate temperature. It also presents an exergy analysis model of flat plate collectors, considering non-uniformity in temperature distribution along the absorber plate. The computation results agree well with experimental data. The ...

This study investigates the unsteady flow phenomena generated from plunging wings with varying flexibility. The experiments were conducted in a wind tunnel with forward flight conditions at a chord based Reynolds number of 5300. The wings are fabricated out of homogeneous isotropic materials with values of 55 and 1702. The conditions of these experiments are matched to previous studies in a wat...

In this paper, the problem of forced convection over a horizontal flat plate under condition of variable plate temperature is presented and the homotopy perturbation method (HPM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. This paper provides good supplements to the existing literature and generalizes the previ...
