Flow of Air through Rocks at Low Rates

Flutter Analysis of a Low Aspect Ratio Swept- Back Trapezoidal Wing at Low Subsonic Flow

A linear, aeroelastic analysis of a low aspect ratio swept back trapezoidal wing modeled as a cantilever plate is presented. An analytical and numerical formulation for both the aerodynamic forcing and structural response of the wing was developed. The analytical model uses a three dimensional time domain vortex lattice aerodynamic method. A Rayleigh-Ritz approach has been used to transfer equa...

An experimental investigation of performance of a 3-D solar conical collector at different flow rates

The shape of a solar collector is an important factor in solar-to-thermal energy conversion. Conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. Flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. The present study is an experimentally investigated of the performance of the solar coni...

Effect of Blade Design Parameters on Air Flow through an Axial Fan

The objective of this paper is the numerical study of the flow through an axial fan and examining the effects of blade design parameters on the performance of the fan. The axial fan is extensively used for cooling of the electronic devices and servers. Simulation of the three-dimensional incompressible turbulent flow was conducted by numerical solution of the (RANS) equations for a model. The S...

Detection of low Intraperitoneal Air

Perforation of a hollow viscus is an acute abdominal drama and the accurate diagnosis highly depends on demonstration of free intra­pritoneal air. The importance of adequate examination in the demonstration of ,tiny amount ()ff air is stressed and the value of an upright chest film when the horizontal beam is tangential to the top of the diaphragm is mentioned. Before standing for chest x-ray t...
