Diffusion & Passive Scalar Transport

Cases that involve transport and diffusion of various substances appear in a variety of engineering and scientific fields including biomedical microfluidics and chemical engineering . Such simulations concern  modelling of drug diffusion, heat transfer, concentration of species and chemical reactions.

QuickerSim CFD Toolbox for MATLAB® handles these types of problems efficiently using the Finite Element Method (FEM) and a selection of numerical schemes. It also involves effective stabilization techniques such as the Streamline Upwind Petrov-Galerkin (SUPG) method to simulate more demanding cases. Standard boundary conditions (Neuman, Dirichlet and Robin) and user-defined source terms are available. The open structure of the QuickerSim CFD Toolbox facilitates implementation of custom models and functions and allows to take full control of the computation.

Take advantage of other features of our software and integrate diffusion and passive scalar transport into more complex cases to simulate chemical reactions and other processes. To learn more about modelling diffusion and passive scalar transport visit out TUTORIAL PAGE .
