Experimental research on performance parameters of a self-excited pulsed jet device

Experimental Investigation on Surface Quality Processed by Self-Excited Oscillation Pulsed Waterjet Peening

High-speed waterjet peening technology has attracted a lot of interest and is now being widely studied due to its great ability to strengthen metal surfaces. In order to further improve the mechanical properties of metals, self-excited oscillation pulsed waterjets (SOPWs) were used for surface peening with an experimental investigation focused on the surface topography and properties. By imping...

Static Pressure Distribution in an Excited Jet: Some Observations (RESEARCH NOTE)

A plane subsonic jet was subjected to periodic oscillations in the near nozzle region by a twin vane system. During excitation, the jet was found to spread significantly and entrain mass much more than its steady counterpart. Time averaged static pressure measured in the flow field with a disc probe exhibited prominent well defined suction regions different from that of a steady jet.

Experimental and CFD Studies on the Effect of the Jet Position on Mixing Performance

Experimental study of piston scuffing effect on engine performance parameters

Piston scuffing is one of the destructive faults in internal combustion (IC) engines. There are different causes to make this fault that lack of lubricant is the most important one among them. The purpose of this paper is the quantitative study of the piston scuffing effects on the engine performance parameters which is a new research direction in the IC engine filed. For this reason, several e...

The Relationship between Self-efficacy in Research and Research Performance A study on Students of Medical Sciences University of Mashhad

Introduction: Research is one of the most interesting areas in which the effects of self-efficacy and confidence have been studied but little attention has been paid to it in Iran. The purpose of this study is to survey the relationship between self-efficacy in research and research performance among students of Medical Sciences University of Mashhad. Methods: This descriptive correlation stud...
