Numerical investigation was performed on NACA 0015 which is a symmetric airfoil. Pressure distribution and then lift and drag forces are verified. Changing of ground clearance was a considerable point. Also the angle of attack was changed from 0° to 10°. Pressure coefficient reaches its higher amounts on the wing lower surface when the ground clearance diminishes. Increment of the angle of atta...
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 compressor rotor blades row. Simulations are carried out on near-stall condition, which is val...
metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...
Linkage was tested between a mucociliary transport polymorphism and resistance/susceptibility to lethal Sendai virus infection in segregant hybrid mice of C57BL/6J and DBA/2J parents. The distribution of paired phenotypes for tracheal mucociliary transport rates and susceptibility to lethal Sendai virus infection in 171 F1 X DBA/2J mice showed strong interaction of the parental phenotypes.
The flow behavior inside the shrouded disk system is of importance in appropriate design of turbomachinery cavities and turbine test cell hydraulics dynamometer. The turbulent incompressible flow is analyzed for the shrouded disk system with axial clearance. The flow core behaves as a Batchelor type structure when a weak inflow is imposed on the disk cavity. By increasing the inflow, the centra...
Introduction: The aim of this study was to determine the effects of linear and nonlinear periodized resistance training on serum levels of creatinine, glomerular filtration rate (GFR), and creatinine clearance in women with abdominal obesity. Materials & Methods: This study was conducted on 42 women who were randomly assigned into linear periodized (LP) resistance training (N=15, age: 40.4...
In developing countries, motorcycle riders typically perform lane filtering at signalized urban intersections. This study aims to determine the factors that affect lateral clearance of as they travel between two lanes mixed traffic intersections in countries. this study, an onboard measurement device was developed measure lane-filtering behavior riders. It installed on a test continuously recor...
