CFD Softwares: Fluent versus Jadim

Two different software are used to simulate the gas injection: FLUENT and Jadim. 

Fluent is a commercial CFD software which provide a wide range of multiphase flow models to model the behavior and interactions of a large number of phases. The user can not have access to the code; therefore, there are no possibilities to check equation implementation or to had function in the code.This software has been largely used in the industry for decades.

JADIM LES is a research code developped by Jacques Magnaudet and Dominique Legendre's team in the Interface group at IMFT(Institut de Mécanique des Fluides de Toulouse). The code permits to describe in an accurate way such physical mecanisms present
in multi-phase fows. It is especially  able to simulate two and three-phases flow with the VOF method without reconstruction of the interface. Jadim resolves Navier-Stokes equations in 3D for incompressible fluids and instationnarities.
A second order space and time finite volum method with a structured mesh is used (third order Runge-Kutta scheme for non-linear term resolution coupled with a Crank-Nicolson scheme for the semi-implicit part). This code can only be used with structured mesh.

The table below compare  the main caracteristics of Jadim and Fluent:

                

It is important to be aware about the difference that exits between the two codes in order to understand simulations issues such as lack of convergence or simulations results such as differences in flow features.
