1. Parametric study on axial compressor performance in design condition

Sarallah Abbasi; Ali Joodaki

Volume 10, Issue 1 , Summer and Autumn 2020, , Pages 271-279


  In This paper, a parametric study of compressor performances was performed by streamline curvature method (SLC). Effects of three input parameters in design process, e.g., number of blades, distribution of blade thickness, and blade sweep angels, on the main objective parameters in aerodynamic design, ...  Read More

2. Favorable Plug Shape of an Aerospike Nozzle in Design, Over and Under Expansion Conditions

ava shahrokhi; sahar noori

Volume 8, Issue 1 , Summer and Autumn 2018, , Pages 1-14


  The influence of the plug shape on the performance of an aerospike nozzle thrust force is studied in different back pressure conditions. To generate smooth plug contours, Cubic B-Spline technique is employed. In the current research, basis functions are obtained using Deboor’s relation. The flow ...  Read More

3. Effects of Different Turbulence Models in Simulation of Unsteady Tip Leakage Flow in Axial Compressor Rotor Blades Row

Sarallah Abbasi; Marhamat zienali

Volume 8, Issue 1 , Summer and Autumn 2018, , Pages 61-74


  Characteristics of rotor blade tip clearance flow in axial compressors can significantly affect their performance and stable operation. It may also increase blade vibrations and cause detrimental noises. Therefore, this paper is contributed to investigate tip leakage flow in a low speed isolated axial ...  Read More
