Heat Transfer, General Introduction, V 4.3Heat Transfer, General Introduction, V 4.3

This PowerPoint document is a general introduction to the heat transfer capabilities of COMSOL Multiphysics and also COMSOL Multiphysics with the Heat Transfer Module. It is organized in 4 parts: -1- Presentation of different thermal...

Open-Hole Multilateral WellOpen-Hole Multilateral Well

Multilateral wells—those with multiple legs that branch off from a single conduit—can produce oil efficiently because the legs can tap multiple productive zones and navigate around impermeable ones. Unfortunately, drilling engineers...

Biot PoroelasticityBiot Poroelasticity

The Poroelasticity interface couples Darcy's law and solid mechanics to assess deformation of porous media that results from fluid withdrawals. The model builds on top of the Terzaghi Compaction example. Results from Terzaghi...

Phase ChangePhase Change

This example demonstrates how to model a phase change and predict its impact on a heat transfer analysis. When a material changes phase, from solid to liquid for instance, energy is added to the solid. Instead of creating a temperature...

Pesticide Transport and Reaction in SoilPesticide Transport and Reaction in Soil

Aldicarb is a commercial pesticide, used on a variety of crops, including cotton, fruits, potatoes, and beans. This arises in the possibility that the general population may be exposed to aldicarb through the ingestion of contaminated...

Forchheimer FlowForchheimer Flow

This is a tutorial model of the coupling between flow of a fluid in an open channel and a porous block attached to one of the channel walls. The flow is described by the Navier-Stokes equation in the free region and a...

Aquifer Characterization through Inverse Modeling from Pump TestsAquifer Characterization through Inverse Modeling from Pump Tests

This model uses the Optimization interface to solve the inverse problem for determining the spatially variable hydraulic conductivity on a discretized quadratic grid from a number of aquifer pump tests. Because the number of...

Pore-Scale FlowPore-Scale Flow

This non-conventional model of porous media flow utilizes Navier-Stokes equations in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya...

Sorbing SoluteSorbing Solute

In this example water ponded in a ring on the ground moves into a relatively dry soil column and carries a chemical with it. As it moves through the variably saturated soil column, the chemical attaches to solid particles, slowing the...

Free Convection in Porous MediaFree Convection in Porous Media

This example treats the modeling of sub-surface flow where free convection in porous media is analyzed. The results are compared with published literature in the field. The model couples the momentum balance to an energy balance...
