This paper presents a two-dimensional Computational Fluid Dynamics (CFD) analysis on the effect of gurney flap NACA 4312 airfoil in subsonic flow. These numerical simulations were conducted for heights 1.5%, 1.75%, 2% and 3% chord length at fixed Reynold Number, Re (5×105) different angle attack (0o ~16o). ANSYS Fluent commercial software was used to conduct these simulations. The flow consider...

The unsteady, incompressible electroviscous fluid flow has been investigated with thermal energy transmission across two parallel plates. upper plate is in motion, while the lower one stationary. governed by Navier-Stokes equations, which are combined Maxwell equation. system of nonlinear PDEs simplified to a ODEs along their boundary conditions using Von-Karman's transformation. For problem's ...

Traditional cooling technologies are now become inadequate for electronic chips due to size reduction and increase in generated heat flux. Microchannel sink (MCHS) is promising candidate its superior performance than competitors. The aim of this study investigate the hydrothermal MCHS with novel trefoil shape ribs. three configurations ribs are: MC-AWTR (all wall ribs), MC-SWTR (side MC-BWTR (b...

A positive surge is associated with a sudden change in flow that increases the water depth and modifies structure channel. Positive surges are frequently observed artificial channels, rivers, estuaries. This paper presents application of Kolmogorov complexity its spectrum to velocity data collected during laboratory investigation surge. Two types were considered: undular breaking For both surge...

The waterjet pump is widely applied in the high-speed marine vessels to exploit various kinds of resources vast ocean. transient cavitating flows a are numerically investigated under non-uniform inflow for purpose revealing correlation mechanism between cavitation and vorticity diffusion as well exited pressure fluctuations. unsteady numerical simulation conducted by using Reynold-Averaged Navi...

This work sprung from my collaboration with Prof. Jim Sturm and his students Richard Huang, David Inglis and John Davis. Richard Huang came up with a brilliant and simple scheme by which a offset array of posts could deterministically separate in a binary manner large objects from small objects with extraordinary precision in a low Reynold number flow. The underlying idea behind this “bump” arr...

A Dataset of Gaze Behavior in VR Faithful to Natural Statistics Brendan John Rochester Institute of Technology, 2017 Supervisor: Dr. Reynold Bailey Eye tracking technology is advancing swiftly and many areas of research have begun taking advantage of this. Existing eye trackers project gaze onto a 2D plane, whether it be the display of a head mounted virtual reality (VR) helmet or an image of a...

The unsteady and random character of turbulent flow motion is a key aspect of the multidimensional modeling of internal combustion engines (ICEs). A typical example can be found in the prediction of the cycle-to-cycle variability (CCV) in modern, highly downsized gasoline direct injection (GDI) engines, which strongly depends on the accurate simulation of turbulent in-cylinder flow structures. ...

Greatly expanding its commitment to cancer research and treatment, the government of Puerto Rico recently earmarked $40 million over the next 5 years for its cancer research infrastructure and another $75 million to build a new cancer research hospital. The Commonwealth of Puerto Rico is in the process of approving the funding for what will be the Caribbean’s first comprehensive cancer center, ...

Vertical axis wind turbines (VAWTs) are gradually receiving more and more interest due to their lower sensitivity to the yawed wind direction. Compared with straight blades VAWT, blades with a certain helicity show a better aerodynamic performance and less noise emission. Nowadays computational fluid dynamics technology is frequently applied to VAWTs and gives results that can reflect real flow...
