Backward-facing step (BFS) is a model that provides several applicative features in engineering. The complex phenomena of BFS flow have crucial impact on any application. Therefore, this study comprehensively investigates the characteristics with various shapes. backward-facing (F-BFS) fillets were tested at intervals Reynolds number 50 smaller than Re 400 using CFD approach. Based computationa...
Flow topology and unsteady cavitation dynamics in the wake of a backward facing step was investigated using high speed videography time-resolved X-ray densitometry, along with static dynamic pressure measurements. The measurements are used to inform understanding underlying mechanisms observed flow as they related shock wave induced instabilities. differences cavity behavior at different number...
Introduction: In the era of increasing development of electronic technology, using technology and making favorable changes in student assessment have a prominent role. The purpose of this study was to review the evolution process of student assessment methods in medical education and report its process in Iran based on the 8-step model) In Line with the Package for Medical Sciences Assessment S...
