Study on the Performance deterioration of Mixed Flow Impeller due to Change in Tip Clearance

引用

Journal of Thermal Science 2013年第6期22卷 532-538页

作者： ramesh Rajakumar.d Ramamurthy.S Govardhan.M National Aerospace Laboratories-Bangalore-560017 NCAd National Aerospace Laboratories Thermal Turbomachines laboratory Department of Mechanical EngineeringIndian Institute of Technology Madras

Performance of mixed flow compressor with un-shrouded impeller strongly depends upon unsteady, asymmetrical flow fields in the axial directions. The flow through the mixed flow impeller is complex due to three-dimensional nature of geometry. In mixed flow impeller, there are clearances between the rotating impeller blades and the casing as the high pressure ratio compressors are usually open shrouded impellers. As a result, certain amount of reduction in the performance is unavoidable due to clearance flows. In the present investigations, numerical analysis is performed using a commercial code to investigate tip clearance effects on through flow. The performance of mixed flow impeller with four different clearances between impeller and stationary shroud are evaluated and compared with experimental results. The impeller performance map was obtained for different operating speeds and mass flow rates with different tip clearances. The result shows that the tip leakage flow strongly interacts with mainstream and contributes to total pressure loss and performance reduction. The pressure and performance decrement are approximately linearly proportional to the gap between impeller and stationary *** analysis showed scope for improvement in design of the compressor for better performance in terms of efficiency and operating range.

World Journal of Gastroenterology 2007年第3期13卷 486-487页

作者： ramesh P Arasaradnam Paul d Hurlstone School of Clinical Medical Sciences Newcastle University Newcastle United Kingdom Academic department of Gastroenterology Sheffield Teaching Hospitals Sheffield United kingdom

TO THE EdITORIn the UK, clear guidelines exist as to the expected level of competence an individual endoscopist should achieve.This is of utmost importance given the variance in practice among endoscopic departments as highlighted by the National Colonoscopy audit in 2002. The audited variables included sedation practice, caecal completion and complication rates, but not the type of instrument used.

Entropy generation analysis of natural convective radiative second grade nanofluid flow between parallel plates in a porous medium

引用

Applied Mathematics and Mechanics(English Edition) 2019年第4期40卷 481-498页

作者： K.ramesh O.OJJELA department of Applied Mathematics Defence Institute of Advanced Technology

The present article explores the entropy generation of radiating viscoelastic second grade nanofluid in a porous channel confined between two parallel plates. The boundaries of the plates are maintained at distinct temperatures and concentrations while the fluid is being sucked and injected periodically through upper and lower plates. The buoyancy forces, thermophoresis and Brownian motion are also considered due to the temperature and concentration differences across the channel. The system of governing partial differential equations has been transferred into a system of ordinary differential equations(OdEs) by appropriate similarity relations, and a shooting method with the fourth-order Runge-Kutta scheme is used for the solutions. The results are analyzed in detail for dimensionless velocity components. The temperature, concentration distributions, the entropy generation number, and the Bejan number corresponding to various fluid and geometric parameters are shown graphically. The skin friction, heat and mass transfer rates are presented in the form of tables. It is noticed that the temperature profile of the fluid is enhanced with the Brownian motion, whereas the concentration profile of the fluid is decreased with the thermophoresis parameter, and the entropy and Bejan numbers exhibit the opposite trend for the suction and injection ratio.
