The flow structure of one isothermal swirling case in the Sydney swirl flame database was studied using two numerical methods. Results from the Reynolds-averaged Navier-Stokes (RANS) approach and large eddy simulation (LES) were compared with experimental measurements. The simulations were applied in two different Cartesian grids which were investigated by a grid independence study for RANS and a post-estimator for LES. The RNG k-ε turbulence model was used in RANS and dynamic Smagorinsky-Lilly model was used as the sub-grid scale model in LES. A validation study and cross comparison of ensemble average and root mean square (RMS) results showed LES outperforms RANS statistic results. Flow field results indicated that both approaches could capture dominant flow structures, like vortex breakdown (VB), and precessing vortex core (PVC). Streamlines indicate that the formation mechanisms of VB deducted from the two methods were different. The vorticity field was also studied using a velocity gradient based method. This research gained in-depth understanding of isothermal swirling flow. 相似文献

This article describes a parallel implementation of an algorithm for simulating mixed convective flow over a three-dimensional backward-facing step. A FORTRAN90 code was developed and parallelized using OpenMP directives for distributed shared memory (DSM) multiprocessors. Numerical experiments conducted on an IBM p5-575 multiprocessor show that the code achieves significant speed-up on up to 16 processors. Superlinear speed-up was also observed in some cases as a result of efficient cache utilization on the multiprocessor. 相似文献

Based on an unperturbed airflow assumption and using a set of validated modelling methods, a series of activities were carried out to optimise an aerodynamic design of a small wind turbine for a built up area, where wind is significantly weaker and more turbulent than those open sites preferable for wind farms. These activities includes design of the blades using a FORTRAN code; design of the nose cones and nacelles, which then constituted the rotor along with the blades; optimisation of the rotor designs in the virtual wind tunnel developed in the first part of the study; and finally, estimation of the annual power output of this wind turbine calculated using hourly wind data of a real Scottish Weather Station. The predicted annual output of the finalised rotor was then compared with other commercial turbines and result was rather competitive. 相似文献

The paper describes a FORTRAN computer program, ISTORE, designed to simulate the optimum operation of an ice-storage air-conditioning system under a time-of-use electricity tariff. The model uses capital cost and operating cost data to optimise the sizes of the component chiller set and store for an annual operating cycle which can take into account several different seasonal load conditions. Where applicable, the model can also optimise settings for maximum electricity demand. The model provides comprehensive graphical and printed output which allows optimum control strategies to be quickly identified. An example study is given which indicates that considerable savings are available under a maximum demand tariff by using the ice-storage technology as a load management device to reduce air-conditioning costs. 相似文献
