Reducing drag is an excellent approach to improving truck efficiency and saving fuel. The addition of the cylinder could be alternative for reduction devices like windshield that has a similar function enhance truck’s aerodynamic performance. A numerical analysis was performed using Ansys Fluent CFD software estimate influence on truck's force. study conducted by comparing without additional ab...

Currently, computational fluid dynamics has become the primary method for analyzing flow state inside machine. Herein, Ansys Fluent software is used to design a more effective oil-field device, namely, gas–liquid cylindrical cyclone (GLCC)-horizontal combined separator. The characteristics of mixed flow, turbulence intensity, and phase volume fraction distribution are analyzed, factors affectin...

Abstract The water level above a hydrokinetic turbine is likely to vary throughout the season and even along day. In this work, influence of free surface on performance three bladed horizontal-axis explored by means three-dimensional, transient, two-phase flow computational model implemented in commercial CFD software ANSYS Fluent 19.0. k – ω SST Transition turbulence coupled with Volume Fluid ...

Large caissons are extensively applied as deep-water foundations in marine engineering. In fact, generally prefabricated and transported to project site by wet towing. Motion responses of large those occurring during the towing process were investigated, CO2 emissions under various conditions calculated. These all considered ensure safety environmental protection. The caisson resistance coeffic...

The fluid mixture hydrocyclone is an excellent tool for downhole oil/water separation (DOWS) high water cut. In the present work flow through inline axial inlet investigated computationally using ANSYS-FLUENT-19 software. three dimensional continuity and momentum equations with SST k-omega turbulence model are used to simulate strongly swirling, turbulent flow. Oil/water two phase treated as wo...

The cause of drag force vehicle accounts high fuel losses. Fuel consumption is adversely affected due to aerodynamic forces, which specially the force. Vehicles that are moving in certain arrangement allows for a significant decrease at highway speeds by reducing on vehicles. In this paper, effect resistance was numerically investigated. models were arranged back-to-back with difference distanc...

Although renewable energy systems have become an interesting global issue, it is not continuous either daily or seasonally. Latent heat storage (LHES) one of the suitable solutions for this problem. LHES becomes a basic element in systems. compensate lack when these are at low production conditions. The present work considered shell and tube numerical investigation rotation influence on melting...

Abstract As a classic problem in oceanographic and coastal engineering hydrodynamics, solitary wave propagation is used to benchmark novel high-fidelity numerical model based on the Navier–Stokes equations. The combines Finite Volume method Merged Stencil with 3rd-order reconstruction (FVMS3) Tangent of Hyperbola for INterface Capturing Quadratic surface representation Gaussian Quadrature (THIN...

Wastewaters from power plants is a major concern for environmental protection. After the water used in thermal plant, heated effluent again discharged same body where it taken. This not only disturbs aquatic life but also affects balance of ecosystem. paper presents background pollution, modelling approach and analysis methods prediction pollution. A two-dimensional model Sava River discussed. ...

The effect of initial bubble diameter on the motion pattern in a flotation column has been studied by twophase computational fluid dynamics (CFD) method. two-phase simulations have done using volume (VOF) model ANSYS® Fluent® software. field was square cross-section with width 0.1 m and height 1 into which air interred as single from lower part an internal sparger. An experimental test also per...
