A steady state laminar natural convection flow in a trapezoidal enclosure with discretely heated bottom wall, adiabatic top wall, and constant temperature cold inclined walls is performed. The finite volume based commercial code "ANSYS-FLUENT" is used to investigate the influence of discrete heating ...

In this study, the two-phase (water and air) natural convection and thermal stratification phenomena with conjugate heat transfer in the rectangular enclosure were investigated numerically using ANSYS Fluent 17.2 code. The transient numerical simulations of these phenomena in the full-scale computational...

I using Fluent 14.0, and I modelling natural convection in the nuclear spent fuel pool, my suggestion is: opent fluent -> help -> Tutorial Guide and find topic "Modelling radiation and natural convection" (in fluent 14.0v 307 page, in the 15.0 version could be another page number). So,...
The Navier–Stokes equations and energy equations have been employed to simulate the flow and thermal behaviors with a finite volume (SIMPLE) method to represent and evaluate the partial differential equations in the form of algebraic equations using ANSYS–FLUENT 16.1 Package. The study has employed...
The numerical model using the ANSYS FLUENT, extended the analysis to other partition numbers. Results showed that the natural convection was significantly strengthened by partitioning the LHSU, which shortens the time required for PCM melting. However, an optimal number of partitions were obtained ...
Initially, a 3D RANS equation with a k-ω SST turbulence model simulation was performed using Ansys Fluent to evaluate the wind-induced pressures on the building surfaces. This analysis helps to understand the impact of external wind on the building surfaces. From the average pressures obtained at...
This investigation carried out numerically by using the commercially available Ansys Fluent Software. The substrate board is oriented in vertical direction and natural convection heat transfer is studied. In addition, the effect of surface radiation of the heat sources is also investigated. The effect ...
