This paper shows how mesh morphing can be effectively used as a tool for updating CFD models of wings into iced configurations, i.e. accounting for the presence of complex shapes originated during ice accretion. Although several approach are well established for the prediction of ice build up, a robust method capable to continuously update the original geometry into the iced one is a paramount ...

The instability of water-sediment flow in fractures can easily induce disasters. Therefore, it is great significance for the prevention and control inrush to study two-phase fractures. Based on theory, a model system was established. Ansys Fluent software used characteristics smooth rough spatial-temporal evolution laws were studied; results indicated that they did not change with time fracture...

The paper presents the results of experimental and model tests transport dispersed fluid droplets forming a cloud aerosol in stream air ventilating selected section underground excavation. excavation for testing is part ventilation network Experimental Mine Barbara Central Mining Institute. For given environmental conditions, such as temperature, pressure, relative humidity, velocity air, distr...

In the current era of globalization every prosperous nation in this world wishes to develop a fast moving aircraft with a high lift coefficient and low drag coefficient, which helps them to enhance their military force and strengthens its civilization’s foundation. The purpose of this study is to examine the viscous, incompressible and steady-state flow over the F-16 aircraft using computer mod...

This study is concern about the behavior of a diesel generator sets in terms sound pressure level and drop. Numerical had been carried out by using simulation from ANSYS software to obtain drop across duct silencer sets. Fluent Harmonic Responses was used perform on silencer. The design 3-dimensional model consists splitter rockwool as its porous medium. Observation focused along process detail...

The purpose of this study is to identify parameters influence on the particle deposition within fin and tube heat exchanger of air-conditioning systems by CFD analysis. First the basic sketch of periodic geometry drawn and meshing operation including boundary conditions was performed. Then the gas side properties and flow parameters were solved by ANSYS Fluent 14.5 software. Lagrangian equa...

The development of advanced artillery needs to be combined with simulation means, so, traditional calculation method and the flow field was employed calculate efficiency a largecaliber muzzle brake we designed, results achieved by these two methods were 47.8% 49.3%, respectively. Further, overpressure value 1 m away from obtained through simulation, far-field calculated using blast wave attenua...

To optimize the deposition parameters of diamond films, the temperature, pressure, and distance between the filament and the susceptor need to be considered. However, it is difficult to precisely measure and predict the filament and susceptor temperature in relation to the applied power in a hot filament chemical vapor deposition (HF-CVD) system. In this study, the temperature distribution insi...

Three-dimensional simulations of diesel particulate matter (DPM) distribution inside a single straight entry for the Load-Haul-Dump loader (LHD)-truck loading and truck hauling operations were conducted by using ANSYS FLUENT computational fluid dynamics software. The loading operation was performed for a fixed period of 3 min. The dynamic mesh technique in FLUENT was used to study the impact of...
