CTRAN/W e CTRAN3D 2021.4


Solute and gas transfer analysis

CTRAN/W is a powerful finite element software product for modeling solute and gas transfer in porous media. CTRAN/W can be used to model simple diffusion-dominated systems through to complex advection-dispersion systems with first-order reactions.

Add CTRAN3D to analyze 3D solute and gas transfer using the same comprehensive set of material models and boundary conditions.

CTRAN/W and CTRAN3D can be used to model a vast array of geo-environmental problems involving the movement of dissolved species or gases that originate from either man-made or naturally occurring sources.

Key Features

Comprehensive Formulation

CTRAN/W and CTRAN3D offer the capability to model a diverse set of solute and gas transport mechanisms including diffusion, advection, dispersion, adsorption, decay, and density-dependent flow due to its comprehensive formulation.

Dual Phase Gas Transfer

CTRAN/W and CTRAN3D model gas transfer in both the gaseous and aqueous phases. A bulk diffusion coefficient, longitudinal dispersivity, and transverse dispersivity are defined for each phase.

Saturated and Unsaturated

CTRAN/W and CTRAN3D are formulated for saturated and unsaturated transport, allowing the coefficient of diffusion to vary with water content and the advection process to adjust as groundwater velocities change in the unsaturated zone.

Sorption and Kinetic Reactions

CTRAN/W and CTRAN3D can model equilibrium sorption and first-order reactions, such as radioactive decay, biodegradation, and hydrolysis.


CTRAN/W and CTRAN3D can model almost any contaminant transport problem

Caesium 137 Transport

Caesium-137 (Cs-137) is an anthropogenic radioactive isotope formed as a product of nuclear fission. The objective of this example is to analyze Cs-137 transport into an unconfined aquifer using CTRAN/W. The effect of adsorption and decay on solute concentrations and mass discharge is highlighted.
