This numerical study investigates the steady state unimolecular thermal decomposition of a chemical dissolved in water inside a parallel-plate reactor containing four heated circular rods using a penalty Galerkin finite element approach. The reactant fluid enters from the left inlet and exits from the right outlet of the reactor. All solid walls of the reactor are assumed to be thermodynamicall...

This study aims to find the best material for manifold and improve airflow in UniMAP Automotive Racing Team (uniART) exhaust manifold. The is a part of system that collects delivers gases from cylinder head outlet. manifold’s design significant engine performance. current new designs were modelled using SOLIDWORKS software. Stainless steel, cast iron mild steel chosen as materials studied by co...

Bladeless fans are more energy efficient, safer due to the hidden blades, easier clean, and adjustable than conventional fans. This paper investigates influence of airfoil’s outlet slit thickness on discharge ratio by varying an Eppler 473 airfoil from 1.2 mm 2 in intervals 0.2 using a k-omega SST turbulence model with all y+ wall treatment used numerically simulate CFD. The computational resul...

The purpose of this study is to validate numerical simulations of flow and pressure in an abdominal aortic aneurysm (AAA) using phase-contrast magnetic resonance imaging (PCMRI) and an in vitro phantom under physiological flow and pressure conditions. We constructed a two-outlet physical flow phantom based on patient imaging data of an AAA and developed a physical Windkessel model to use as out...

Feature tracking of approximately annually separated Landsat-7 ETM+ imagery acquired from 1999 to 2010 and speckle tracking of 24-day separated RADARSAT-2 imagery acquired from 2009 to 2015 reveal that motion of the major tidewater glaciers of Devon Ice Cap is more variable than previously described. The flow of almost half (six of 14) of the outlet glaciers slowed over the observation period, ...
