Performance Study on The heat-transfer characteristic of a LVG in Different Sizes
In this paper,a new type of LVG were tested and the results show that it has good heat transfer function and pressure drop characteristic.In order to obtain the related functional influences of the newly LVG in different parameters,a three-dimensional numerical simulation was made.The result indicates that the perturbation effect of the same LVG at a lower current speed is better than the effect of a high speed.Inorder to avoid the breakdown of the vortex very quickly,the LVG sizes should be decreased appropriately when the current speed is high; to generate effective longitudinal vortex,the LVG must have large enough size and width,when the ratio of width to height is H=2,the effect is better than H=1; it is ideal for the attack angle of LVG in low speed zone to take Forty five degree angle.
