In the present study, computational fluid dynamics (CFD) simulation were performed to investigate the drop formation in single holes in a solvent extraction. The effects of various operating and design parameters on the drop formation were investigated in order to optimize the drop formation. Simulation results indicated that CFD simulations can give useful information about the drop formation ...

The purpose of this study was to propose an innovative approach of setting outlet boundary conditions for the computational fluid dynamics (CFD) simulation of human common carotid arteries (CCAs) bifurcation based on the concept of energy loss minimisation at flow bifurcation. Comparisons between this new approach and previously reported boundary conditions were also made. The results showed th...

Nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. It is almost used as a first and the most applicable choice in separation methods. In this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. The study was carried out by using a 3-D...

a novel computational fluid dynamics and molecular kinetic theory (cfd-mk) method was developed to simulate the impingement of a nanodroplet onto a solid surface. a numerical solution of the navier–stokes equation using a volume-of-fluid (vof) technique was used to model nanodroplet deformation. dynamic contact angle during droplet impact was obtained by molecular kinetic theory. this dynamic c...

Integrated gasification combined cycle (IGCC) plants have significant advantages for efficient power generation with carbon capture. Moreover, with the development of accurate CFD models for gasification and combined cycle combustion, key units of these processes can now be modeled more accurately. However, the integration of CFD models within steady-state process simulators, and subsequent opt...

UNLABELLED With the capability to improve indoor air quality while simultaneously reducing energy demand, displacement ventilation is becoming popular. However, the numerical simulation of air distribution in an indoor space with displacement ventilation using computational fluid dynamics (CFD) is challenging because of the complexity of air diffuser geometry and the complicated airflow pattern...

Over the last decades, the analysis of transients and accidents in nuclear power plants has been performed by system codes. Though they will remain the analyst’s tool of choice for the foreseeable future, their limitations are also well known. It has been suggested that an improvement in the simulation technology can be obtained by “coupling” system codes with Computational Fluid Dynamics (CFD)...

Wave generation methodology has been developed and validated by simulating wave in CFD. In this analysis, Flap type wave maker has been modeled numerically with wave basin to generate waves for marine experimental analysis. Irregular waves are arrived from the wave spectrum, and this wave has been simulated in CFD. Generated irregular wave has been compared with an analytical wave. Simulated wa...
