Internal Flow Visualization of a Diagonal-Flow Fan with an Inlet Annular Wing

Flow Visualization Around a Non - Circular Tube

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

Investigation into Influence of Inlet Prewhirl on Flow Field of Diagonal Impeller with Exit Guide Volute

By means of setting inlet pre-rotator ,the inlet and exit flow field of the diagonal flow impeller with exit guide volute have been measured with 5 holes probe, in different flow conditions, and in the conditions of positive and negative pre-rotating. The expe1iment results are compared with that of without the pre-rotator.

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...

Determination of Dynamic Instability Speed of an Unsweep Wing in Subsonic Flow Including Compressibility Effects

In this paper, the equation of motion of an elastic 2 DoF wing model has been derived using Lagrange's method. The aerodynamic loads on the wing were calculated via the Strip-Theory and the effect of compressibility was included. Wing deflections due to bending and twist motions were determined using the Assume-Mode method. The aeroelastic equations were solved numerically using the V-g method....
