The log-wake law was successful in mapping velocity fields for uniform flow over flat surfaces, even cases of wake effects (velocity dips, wall effects, and secondary currents). However, natural riverbeds with undulations bedforms challenge these models. This study introduces a moment-based empirical method rough estimation the stationary 2D bedforms. It proposes three polynomial profile templa...

In this paper, free convection flow and heat transfer of nanofluids of differently-shaped nano-sized particles over a vertical plate at very low and high Prandtl numbers are analyzed.  The governing systems of nonlinear partial differential equations of the flow and heat transfer processes are converted to systems of nonlinear ordinary differential equation through similarity transformations. T...

An extensive experimental investigation to study the flow structure over the wing of a fighter type configuration model has been conducted. The model used for this study was similar to the High Alpha Research Vehicle (HARV) that has been used in various European research centers for studying its force and moment characteristics. Tests were conducted at two subsonic speeds and at low to moderate...

Velocity distributions are an enhanced representation of image velocity implying more velocity information than velocity vectors. Velocity distributions allow the representation of ambiguous motion information caused by the aperture problem or multiple motions at a given image region. Starting from a contrastand brightness-invariant generative model for image formation a likelihood measure for ...
