Reducing Pressure Drop in Microscale Channel Using Constructal Theory
The effectiveness of microchannels in enhancing heat transfer has been demonstrated in the semiconductor industry. In order to tap the microscale heat transfer effects into macro geometries, overcoming the cost and technological constraints, microscale passages were created in macro geometries machined using conventional fabrication methods. A cylindrical insert was placed within a pipe, and ge...
متن کاملApplication of Response Surface Methodology for Modeling and Optimization of the Cyclone Separator for Minimum Pressure Drop
A Response surface design of experiment has been performed based on the Muschelknautz method of modeling (MM) for 64 test cases using Box-Behnken design to study the effect of seven geometrical cyclone dimensions on the pressure drop and cut-off diameter. It is found that the most significant geometrical parameters are, the vortex finder diameter, the inlet section width and height, and the cyc...
متن کاملReexamination of Tropical Cyclone Wind–Pressure Relationships
Tropical cyclone wind–pressure relationships are reexamined using 15 yr of minimum sea level pressure estimates, numerical analysis fields, and best-track intensities. Minimum sea level pressure is estimated from aircraft reconnaissance or measured from dropwindsondes, and maximum wind speeds are interpolated from best-track maximum 1-min wind speed estimates. The aircraft data were collected p...
متن کاملPressure Drop in Microchannels Filled with Porous Media
The pressure drop in microchannels filled with porous media formed by square arrays of cylinders (micro-porous channels) is investigated. Combining the Brinkman equation and the existing models for permeability of regular arrays of cylinders, the pressure drop in the considered micro-porous channels is calculated theoretically. Soft lithography method is used to fabricate several Polydimethylsi...
