Assessment of the turbulence models for modelling of bubble column
(The Institution of Engineers, Malaysia, 2009-12)This paper presents an Eulerian two-fluid modelling of the gas-liquid flow in a bubble column. The influence of the bubble size, turbulence models and the grid size on the gas hold-up and the axial liquid velocity were ... -
CFD investigation of fluid flow and turbulence field characteristics in a four-stroke automotive direct injection engine
(The Institution of Engineers, Malaysia, 2008-03)The CFD simulation to investigate the effect of piston crown inside the combustion chamber of a 4-stroke direct injection automotive engine under the motoring condition is presented. The analyses are dedicated to investigate ... -
Computational analysis of hemodynamic effect on mismatch end-to-end reverse saphenous vein graft diameters
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)Artery reconstruction in upper extremities is rare performed compared to the incidence of reconstruction in lower extremities. Primary vascular repair was performed in many cases. An interposition vein graft or venous ... -
Computational analysis on upper extremity vein graft: simulation on kinked vein graft
(Elsevier Ltd., 2012)An artery reconstruction in upper extremities is rare performed compared to the artery reconstruction in lower extremities. Primary vascular repair was performed in many cases. As to alleviate vascular occlusion, an ... -
Computational fluid dynamic analysis on microvascular vein grafting: effect of mismatched conduit diameters
(IEEE Conference Publications, 2012)An artery disease of upper extremity is uncommon happened. The most common cause of artery disease in upper extremity is atherosclerosis. In few patients with artery disease, surgical vein bypassing or vein interposition ... -
Computational fluid dynamics analysis of shelland-double concentric-tube heat exchanger
(IEEE Conference Publications, 2011)A shell-and-double concentric-tube heat exchanger is a new invention in heat transfer devices that is used for transfer of internal thermal energy between three fluids at different temperatures. The structure of the ... -
Effective thermal conductivity for melting in PCM encapsulated in a sphere
(Elsevier Ltd., 2014-06)Heat transfer in phase change materials (PCMs) contained in spherical encapsulations can be modelled more simply if an effective thermal conductivity can be determined to represent the natural convection occurring within ... -
A preliminary study of inhaled pharmaceutical aerosol flow characteristics in metered dose inhaler spacer
(Springerlink, 2008-06-25)Metered Dose Inhalers (MDI) is used to prevent and relieve the symptoms and progression of certain diseases (asthma, chronic obstructive pulmonary disease, cystic fibrosis and bronchiectosis) by delivering the inhaled ... -
Theoretical approach on vein graft survival: Simulation on vein graft
(Inderscience Enterprises Ltd., 2013)Artery reconstruction in upper extremities is rare performed compared to artery reconstruction in lower extremities. Primary vascular repair was performed in many cases. An interposition vein graft or venous bypass grafting ... -
