Using COMSOL® to Create Passive Intake Velocity Profile CFD Reports

Johnson Screens® was founded in 1904 by Edward E. Johnson of St. Paul, MN, after he invented the world's first "continuous slot wire wrapped well screen”, a big technological advancement of the day. Over the years, Johnson Screens® expanded its water-well screening technology into industries such as surface water treatment, food and beverage processing, pulp and paper, oil and gas, mineral and aggregate processing, and petrochemicals.

Natural sources of water are vital to our way of life. We use water that comes either by way of public water supply systems or directly from wells or springs. We must treat water from lakes, rivers, or oceans before it is usable, even if it is not intended for human consumption. For example, water for cooling or generating steam in power plants and industrial processes has to be free of debris so as not to clog pumps, valves, pipes, or machinery.

Johnson Screens® uses passive intakes to block debris without harming fish and other wildlife. We use COMSOL Multiphysics® to ensure that we maintain an even through-slot velocity distribution across the screen and guarantee that the maximum slot velocity is no more than 0.50 ft/s as required by EPA 316B. The EPA requires this to minimize the possibility of entrainment of small fish and fish eggs.

Computational Modeling of Drug Transport in Arterial Tissue

Arterial tissue consists of cells embedded in an extracellular matrix. Drug molecules delivered to the tissue reside in both intracellular and extracellular compartments. However, it is the intracellular concentration of the drug that is critical for its pharmacological effect. The dose-response relationships obtained from cell culture studies cannot be directly related to the tissue drug concentrations in vivo. The drug may bind to both extracellular and intracellular macromolecules in the tissue. In order to connect the data obtained from cell culture studies with that obtained from animal studies, it is necessary to determine what fraction of the drug is in free form and what fraction of it is in bound form in the tissue. A mathematical model combined with in vitro experiments can provide a framework to approach this task.

Another Way to the Liver: Tissue Ablation from the Vasculature

RF ablation is an extremely useful medical technique in which diseased tissue is destroyed using an electrically active catheter to induce Joule heating in the targeted tissue. The Heat Transfer Module, an add-on product to the COMSOL Multiphysics® software, includes an example in which an RF trocar is introduced directly into solid liver tissue and used to destroy a tumor. However, in many cases, it is more convenient to access the disease site by threading the catheter through nearby arteries or veins. We use COMSOL Multiphysics® to explore how the liver ablation changes when the trocar is in the hepatic vein. We study how blood flow in the hepatic vein changes the temperature distribution in the tissue as well as how to account for those effects.

Coffee Break
