چکیده
lin apparatus ,·,hieh could produce known amounts of angular momenlum in a pipeline was verified by direct measurement of axial and tangential velocity profiles. By using the assumption that a vortimetcr, with vanes spanning only the rotational core, responded to an equivalent solid rotational core, an expression was develop ed relating the angular velocity to the angular momentum. Comparison of the angu lar velocity Which the swirl generator should pr~luce if angular momentum were conserved to that Measured by the vortiMeter showed excellent agreel':lent.

Estimate the Performance of Catalytic Converter Using Turbulence Induce Devices
In this manuscript, the experimental setup was designed and fabricated for optimizing the parameters of a catalytic converter of INDICA V2 exhaust system. Three turbulence intensify devices, namely Swirl Venturi, Swirl Blades and Swirl Contour, were close-fitted before the catalytic converter. The heating element is embedded in its body and thermocouples are used for knowing the performance at ...
متن کاملEmission Reduction Strategies for Small Single Cylinder Diesel Engine Using Valve Timing and Swirl Ratio
Small diesel engines are widely used for commercial vehicle and passenger car applications due to their higher torque requirements, fuel economy, and better thermal efficiency. These engines are exposed to different operating and environmental conditions and hence emissions from these engines are erratic. Strategies are required to enhance performance and reduce engine-out emissions considering...
متن کاملRotating injector in DI diesel engine for improving performance and reducing NOx emission
Oxides of Nitrogen are the major emission from a diesel engine. It is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of NO is promoted. Various techniques are therefore employed to reduce the NOX emission like EGR, SCR, etc. In this present work a rotating injector is a tec...

متن کاملInvestigation of the effects of using ribs on cyclone’s vortex finder on its performance
Introduction: Generally, geometrical parameters of the cyclone have a profound effect on determining its performance. The air outlet (Vortex Finder) as one of the cyclone’s components has a significant impact on the cyclone’s internal flow pattern, pressure drop and even dust removal efficiency. Material and Methods: Two different air outlets were designed in order to be easily installed and r...
