Flanged diffuser can improve hydrokinetic turbine efficiency. However, in the current literature it is still not clear if flange allows possibility of cavitation on its structure, and whether support high pressure variation. This work presents a Computational Fluid Dynamics (CFD) study effect flanged diffuser. The water flow through was evaluated using Reynolds Averaged Navier Stokes approach c...

in this study, a one-dimensional model called dyresm was used to simulate the thermal structure and artificial destratification of 15-khordad reservoir over a period of one year. the simulation showed that the reservoir is warm monomictic and is stratified during 210 days of the simulation year. the model reproduced the temperature of the meta- and hypolimnion very close to the observed data, b...

Model – Contains all information relevant for a CFD simulation like mesh specifications, volume and boundary conditions, initial conditions, needed solver output, etc. Simulation set-ups are defined through classes, relations and attributes in an object oriented approach avoiding issues encountered with history based strategies. Abstract Models are shape and CAD system independent but CFD solve...

Air distribution of HVAC systems is the most popular type used in building sector, having a relevant impact on indoor air quality and occupant wellness. Many types research developed optimal solutions for system’s design, focusing specific components system, airflow geometry ducts, size shape position diffusers. However, few works literature proposed globally experimental simulation analysis an...

The purpose of this research is to explore the world Computer-Aided Modelling and then apply its tools benefit automotive sector. Three commercially available economical vehicles in Pakistan, namely (i) Daihatsu Mira X, (ii) Honda N-One (iii) Suzuki Wagon R, have been virtually modelled Design (CAD) software by using CATIA-V5R19. This focuses on providing all steps that are needed transform an ...

air pollution is one of the major issues about the diesel engines in todays' world. it is a special concern in those areas that have difficulty meeting health-based outdoor air quality standards. natural gas has low emission and resource abundance and also conventional compression ignition engine can be easily converted to a dual fuel mode to use natural gas as main fuel and diesel as pilo...

Energy simulation (ES) and computational fluid dynamics (CFD) provide important and complementary information for building energy and indoor environment designs. A coupled ES and CFD simulation can eliminate many assumptions employed in the separate ES and CFD computations and thus provide more accurate results. Through theoretical analysis and numerical experiment, this study verified that the...
