Transient Diffusion Modeling of Methane Plume and Source Localization
Methane detection and quantification is of great importance due to its natural abundance, potential to cause explosions and known greenhouse effect. Leak detection and concentration monitoring at source is highly challenging as CH4 is odorless and colorless. This can be performed ... En savoir plus
Validation of Supercritical Fluid Extraction Model with COMSOL Multiphysics® Software
This paper shows the solution of mathematical model of supercritical fluid extraction process, given by Sovova H., 1994, through COMSOL Multiphysics® software. Sovova et al., 1994 used this model for the supercritical CO2 extraction of grape seed. Extraction was performed with different ... En savoir plus
Simulation of a Supercritical Fluid Extraction Process Using COMSOL Multiphysics® Software
In the present work, COMSOL Multiphysics® software was used to solve a mass transfer based mathematical model (Stastova et al., 1996) which is a modified form of Sovova H.,1994 model. The modification has been brought about by introducing the term ‘Grinding efficiency’ in the model and ... En savoir plus
A Dynamic Simulation of Heterogeneous Catalysis with COMSOL Multiphysics® software
Reaction-Diffusion equation is simulated for heterogeneous catalytic reaction involving a porous catalyst particle surrounded by liquid reactants. COMSOL Multiphysics® software along with transport of dilute species module is used for this purpose. Global Variables such as reaction ... En savoir plus
Simulating Light Propagation during I-PDT of Locally Advanced Head and Neck Cancer
Interstitial photodynamic therapy (I-PDT) can be applied for the treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The complex anatomy of LA-HNSCC requires careful planning of the light delivery and fiber insertion. We have developed an image-based approach, ... En savoir plus
A Flow and Transport Model of Catalytic Multi-Pump Systems with Parametric Dependencies
This poster studies catalytic micropumps and their ability to induce fluid flow on the microscale. The goal of the study is to design a long-distance, directed convective loop. An array of catalytic micropumps was constructed in the domain, comprised of two distinct catalysts in an ... En savoir plus
Effect of Viscosity of Food on Digestion and Nutrient Absorption in the Human Small Intestine
Digestion is the process of breaking down food into smaller components, by mechanical and enzymatic action in the digestive tract, so that the smaller nutrient molecules can be more easily absorbed in the intestinal tract. To study and analyze the human digestive process, different ... En savoir plus
Modeling of Mixing-Sensitive Pharmaceutical Drug Substance Processes in Batch Reactors
Manufacturing of pharmaceutical drug substances involves chemical unit operations that are dependent on effective mixing, particularly reactions and crystallizations. Poor mixing can cause uneven distribution of chemical species in stirred tanks, leading to impurity formation and ... En savoir plus
Analysis of Deformation of a Liquid Packaging Made With Board of the LPB Type
The liquid food product packaging are today predominantly made with board LPB type board (Liquid Packaging Board) composite formed by board, which offers mechanical strength, polyethylene, constituent responsible for protection against the passage humidity, and aluminum foil, which helps ...
