Q3DRM - Version 1.0 - CFD Software for Quasi 3D Refinedly Modeling
Optional depth-averaged two-equation closure turbulence models in Q3drm1.0 software & Uses
Depth-averaged two-equation closure turbulence models：
1. Depth-averaged k-ε Model, which was offered by McGuirk and Rode from ‘standard’ k-ε in 1977.
2. Depth-averaged k-w Model, which was build by the author of this software in his 1988’s PhD Thesis, according to the ‘standard’ k-w model, proposed by Ilegbusi and Spalding in 1982.
3. Depth-averaged k-ω Model, which was established by the same author in 2009, according to the famous ‘standard’ k-ω model, proposed by Saffman but popularized by Wolcox in 1998.
Uses:
Q3drm1.0 can be used to simulate, predict and analyze various scientific and engineering problems in shallow waters, such as open channels, the middle and lower reaches of rivers, lakes, reservoirs, cooling pools, estuaries and coastal arears. These problems are closely related to flow, mixing, and the discharges and transports of contaminants and waste heat, e. g. river pollutions, accidental discharges, water resources security, water environment protect, environmental engineering/assessment, comparison between different schemes for water supply and drainage, as well as the impact analysis of discharges on channel safety and so on (covering water conservancy, environment, energy, port and waterway, civil engineering and other fields).
Main features of Q3drm1.0 software
●To solve iteratively the hydrodynamic fundamental governing equations through FVA and spatially collocated variable arrangement on non-orthogonal body-fitted multi-grid.
●Single-layer or multi-layer grids may be smooth/non-smooth; transverse grid nodes may be uniform/non-uniform; and grids may be orthogonal/non-orthogonal.
●Inlets with uniform/non-uniform velocity distributions, conventional outlet, wall and symmetry boundaries (open boundary).
●To provide users with a function of trial calculation for determining the depth-averaged velocity profile at the mainstream entrance section on each layer grid，which obeys the exponential distribution.
●In addition to conventional wall-functions for vertical bank boundary, Q3drm1.0 software also provide the skills for estimating approximately the wall-functions in the regions with sloping bank.
●The software focus on the refined simulations of flows and contaminant transports in complex shallow waters, including meandering riverbanks, multiple islands and bifurcated inlet.
●The software can deal with various discharge schemes of pollutant and waste heat, encountered frequently in engineering, including side-discharge, point-source discharge and point-sink, as well as area-source discharge from the slope along bank.
●Users can observe the bottom topography and generated grids by using section browser and grid browser；and display and analyze the calculated results by using profile browser, field browser and 3-D browser, respectively.
●Users can analyze and compare the distributions of numerical results along specified grid lines, calculated by using different turbulence closure models.
●Q3drm1.0 software provide 16 repeatable computational examples to users, for which the simulations by using three depth-averaged two-equation closure turbulence models have been carried out on coarse and fine two-layer's grids.
