openfoam

The OpenFOAM (Open Field Operation and Manipulation) is an open source CFD toolbox produced by OpenCFD Ltd from UK. It can simulate anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics, electromagnetics and the pricing of financial options.

The core technology of OpenFOAM is a flexible set of efficient C++ modules. These are used to build a wealth of: solvers, to simulate specific problems in engineering mechanics; utilities, to perform pre- and post-processing tasks ranging from simple data manipulations to visualisation and mesh processing; libraries, to create toolboxes that are accessible to the solvers/utilities, such as libraries of physical models.

Simulating dynamic tanks in EMSO (Part 1) Email This Post Print This Post

This post starts to our section of HOW-TO texts. My objetive with this specific post is to introduce using some free tools to different applications.

A classic problem in process engineering is the case of a dynamic tank where the output flow is proportional to its level (Fig. 1). This example is part of EMSO tutorial so that more details would be to consult in the EMSO manual.

In this approaching, the problem of dynamic tank involves 3 variables and 2 parameters such below:

ReactorLab Email This Post Print This Post

The Reactor Lab is a didactic software program that provides simulations of a variety of chemical reactors. Students can actively learn about chemical reactions and reactors by performing experiments and analyzing data – quickly, safely, and inexpensively. The program can be downloaded free of charge and is available for most computers and in English, Spanish, and Portuguese. The Lab is not a general purpose simulator.

Sim42 Email This Post Print This Post

Simulator42 is an open source process simulator project with the goal of providing an affordable and accessible chemical process simulator to the chemical engineering community.

Some interesting features of the project:

  • It is being written in the Python language.
  • The simulator core has been designed to be independent of both user interfaces and thermo providers.

ASCEND Email This Post Print This Post

ASCEND is an open source modelling environment and solver for large or small systems of non-linear equations, for use in engineering, thermodynamics, chemistry, physics, mathematics and biology. Solvers for both steady and dynamic (NLA & DAE) problems, are provided. It offers:

– An object-oriented model description language for describing your system,

– An interactive user interface that allows you to solve your model and explore the effect of changing the model parameters, and
