modeled biomass boiler using Fluent coupling with separated submodules to calculate the behavior of fuel-bed [2,3]. By separating the calculation, the interaction between the fuel-bed and the fluid is difficult to observe. Alternatively, the packed bed could be modeled as part of the ...
The thermal hydraulics part (steady VOL. 46, NO. 6, JUNE 2009 574 state and transient) is restricted to HTRs and to two spatial dimensions. The code can simulate the reactor operation from the initial core towards the equilibrium core. In Turkey, the temperature and the flow distributions ...
1. It shows a singly and one doubly connected two dimensional bodies of arbitrary shape with uniform thermal conductivity. The bodies are bound by a number of curves (S1, S2, … , Sn). Out of them some are isothermal (T1 and T2) while the others are adiabatic. However, the isothermal...
This work considers the flow field as two-dimensional turbulent flow and studies the steady-state properties of heat transfer and the pressure of the suspension nozzle. An adiabatic wall parallel to the moving wall and two slit entrances at either end of the adiabatic wall make up the rectangula...
The numerical algorithm has been implemented in an advanced, general-purpose CFD code, FLUENT, and validations have been carried out for a range of steady-state and unsteady flows, including a 2D axisymmetric orifice, a 3D fuel injector, a radial liquid pump, and a vane pump. The results ...

3D steady-state RANS CFD simulations were performed for 24 reference wind directions (θ) using the realizable k-ε turbulence model for closure (Shih et al., 1995). The choice for the realizable k-ε turbulence model was based on the accuracy and reliability proven by 3D steady RANS simulat...
