2016bSR2 Release Announcement

The new version of edcPisoFoam is now released after the long-term intensive testing. edcPisoFoam is known for its state-of-the-art solver which incorporates the EDC-closure for the turbulence-chemistry interaction with the detailed chemistry approach. The transient PISO-based solver for compressible flows allows coupled with the advanced turbulence modeling capabilities allows to simulate the unsteady combustion physics (of non-premixed and premixed flames, including such phenomenas as heat transfer, pollution formations, combustion dynamics, lean extinguish, etc.) in very accurate and efficient manner.

Validation & Verification

Main Features (2014bSR)

The edcPisoFoam solver was developed based on the finite-volume method and the PISO algorithm for the pressure-velocity coupling, implemented according to Rhie and Chow type interpolation for the cell-centered data storage structure. Note, that the present is based on OpenFOAM® v2.1.x.

Both compressible unsteady RANS (including the family of k-ε and k-ω models) and compressible LES (eddy-viscosity type of SGS models are supported, including k-equation and Smagorinsky) approaches are availbale for predicting turbulence.

The Eddy-Dissipation Concept is used for the turbulence-chemistry interaction with a detailed chemistry approach. For this purpose, the concept of the Perfect Stirred Reactor is utilized with different chemical kinetic mechanisms. The robust RADAU5 algorithm is used to calculate the species reaction rate. The RADAU5 algorithm designed for the solving stiff ODE systems applies a 5th order accurate implicit Runge-Kutta method based on the Radau quadrature formula.

The thermal radiation could be treated using the P-1 approximation or Discrete-Ordinate method (fvDOM). The absorption coefficient and the emission coefficient are calculated using a weighted-sum-of-gray-gases model (WSGGM) or a grey-mean model.
