NUMERICAL SIMULATION OF THE INFLUENCE OF A FILLET AND A BULB ON THE SECONDARY FLOW IN A COMPRESSOR CASCADE

Large fillet radii are typically found on highly loaded compressor rotors to ensure structural integrity.The objective of this paper is to investigate the impact of such real geometry effects on the flow at the hub section.Investigations were performed numerically for the idealised case of a plane compressor cascade with the 3D Navier-Stokes code T

Context: Health care workers (HCWs) are at high risk of COVID-19 infection but data on the risk factors for exposure and infection rate among Indian HCWs are limited.Aims: Our study aims to identify the risk factors and behavior of HCWs which vista 5 vl5 make them high risk for COVID-19 infection and the infection rate among them.Settings and Desig
