Powerful software simulates how chemical reactions occur and change as fluids travel underground.
Developed by researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (LBNL), CrunchFlow is a powerful software package that simulates how chemical reactions occur and change as fluids travel underground. CrunchFlow includes a number of chemical and physical processes that similar products do not, such as changes in how easily water can move through porous media. All of these features are available in a single package that users with a variety of expertise can run on a desktop computer. With CrunchFlow’s computational efficiency, scientists can achieve high spatial resolution while extending simulations far back in geologic time. By improving the accuracy of a range of Earth and environmental sciences applications, CrunchFlow helps scientists better understand current and past ecological systems below the Earth’s surface.
The principal developer is LBNL’s Carl Steefel with co-developers Sergi Molins-Rafa and Jennifer Druhan from the University of Illinois-Champaign.
