Computational Investigations on the Effects of Gurney Flap on Airfoil Aerodynamics
TL;DR: From the computational investigation, it is recommended that Gurney flaps with a height of 1.5% chord be installed perpendicular to chord and as close to the trailing edge as possible to obtain maximum lift enhancement with minimum drag penalty.
Journal ArticleDOI
Computational investigation of impeller—diffuser interaction in a centrifugal compressor with different types of diffusers
S. Anish,Nekkanti Sitaram +1 more
TL;DR: In this article, the performance of a centrifugal compressor with different types of diffusers under various levels of impeller interaction was analyzed using commercial software ANSYS CFX, where the interaction level was varied by varying the radial gap between the impeller and diffuser.
Journal ArticleDOI
A Numerical Study of the Unsteady Interaction Effects on Diffuser Performance in a Centrifugal Compressor
Journal ArticleDOI
Effect of Reynolds Number on Aerodynamics of Airfoil with Gurney Flap
TL;DR: In this paper, the effect of variation in Reynolds number on the aerodynamics of the NACA 0012 airfoil without and with a Gurney flap of height of 3% chord is presented.
Journal ArticleDOI
Conjugate Heat Transfer Analysis on the Interior Surface of Nozzle Guide Vane with Combined Impingement and Film Cooling
TL;DR: In this paper, the effect of conjugate heat transfer on a first stage nozzle guide vane (NGV) of a high pressure gas turbine which has both impingement and film cooling holes was investigated.
