The heat transfer for a non-Newtonian power-law fluid over a moving surface is investigated by applying a uniform suction/injection velocity profile. The flow is influenced by internal heat generation/absorption. The energy equation is solved at constant surface temperature condition. The Merk-Chao series is applied to obtain a set of ODEs instead of a complicated PDE. The converted ordinary diffe...

A new catheter which measures instantaneous changes in coronary artery blood flow velocity is described. The linear relationship between flow velocity is described. The linear relationship between flow velocity measured with the catheter and volume flow through small arteries is documented with a correlation coefficient of 4=0.99. Coronary flow velocity has been measured from the proximal right...

We study inelastic gases in two dimensions using event-driven molecular dynamics simulations. Our focus is the nature of the stationary state attained by rare injection of large amounts of energy to balance the dissipation due to collisions. We find that under such extreme driving, with the injection rate much smaller than the collision rate, the velocity distribution has a power-law high energ...

First published May 6, 2011; doi:10.1152/ajpheart.00080.2011.—Coronary flow reserve (CFR) is an important index of coronary microcirculatory function. The objective of this study was to validate the...

Preformed Particle Gels (PPGs) treatment is one of the most promising solutions to improve conformance control in mature water flooded oil reservoirs. It is very important to be able to evaluate and predict performance of PPGs in porous media. In this paper, we will first introduce new class of enhanced PPGs designed for harsh reservoir conditions (high salinity and temperature) and then pr...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...
