The widespread use of squirrel cage fans, especially in ventilation and home and industrial environments, has led to the formation of many research efforts to improve performance and reduce the sound produced by this type of fan. In the literature, the most important factor in generating sound in this category of fans is the confrontation between the rotor exit flow and the volute of the fan. I...
abstract alluvial fans are the most striking phenomena o fluvial geomorphology . these forms are found in frount of mountains and pediments of arid and semiarid zones . alluvial fans are affected by climate changes and tectonics . occurring of tectonic events lead to reaction of alluvial fans . some of these reactions appear on dissection of alluvial fans and displacement of depocenters on allu...

The paper deals with 21 valid species of the genus Thagria from Guangxi Autonomous Region, China. Eight new species are described and illustrated: T. biprocessa Fan & Dai, sp. nov., T. decussata Fan & Dai, sp. nov., T. irregularis Fan & Dai, sp. nov., T. multispinosa Fan & Dai, sp. nov., T. paramultipars Fan & Li, sp. nov., T. triangula Fan & Li, sp. nov., T. trifasciata Fan & Li, sp. nov. and ...
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...
