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 ... Per saperne di più

Validation of Supercritical Fluid Extraction Model with COMSOL Multiphysics® Software

V. Devi [1], R. Bhargava [1], S. Khanam [1],
[1] Indian Institute of Technology Roorkee, Uttarakhand, India.

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 ... Per saperne di più

Simulation of a Supercritical Fluid Extraction Process Using COMSOL Multiphysics® Software

B. Suryawansi [1], B. Mohanty [1],
[1] Indian Institute of Technology Roorkee, Uttarakhand, India.

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 ... Per saperne di più

Simulating Light Propagation during I-PDT of Locally Advanced Head and Neck Cancer

E. Oakley [1], H. Arshad [1], G. Shafirstein [1],
[1] Roswell Park Cancer Institute, Buffalo, NY, USA

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, ... Per saperne di più

A Flow and Transport Model of Catalytic Multi-Pump Systems with Parametric Dependencies

A. Sen [1], D. Myers [1], A. Altemose [1],
[1] Department of Chemistry, Pennsylvania State University, University Park, PA, USA

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 ... Per saperne di più

Effect of Viscosity of Food on Digestion and Nutrient Absorption in the Human Small Intestine

J. S. Karthikeyan [1], D. Salvi [1], M. V. Karwe [1],
[1] Rutgers University, New Brunswick, NJ, USA

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 ... Per saperne di più

Modeling of Mixing-Sensitive Pharmaceutical Drug Substance Processes in Batch Reactors

F. Akpinar [1], B. Cohen [1], J. Tabora [1], A. Glace [1], K. Lauser [1], F. Lora Gonzalez [1], J. Albrecht [1],
[1] Bristol-Myers Squibb, New Brunswick, NJ, USA

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 ... Per saperne di più
