CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate. The developed correlations were used to extend the model developed by ElGamal et al. (2013) for thin-layer rice drying to volumetric heat and mass transfer in a ...

Comprehensive studies of drug transport in nanofibres based mats have been performed to predict drug release kinetics. The paper presents our approach to analyze the impact of fibers arrangement, one of the parameters varied in our parallel experimental studies. COMSOL Multiphysics® has been used to assess the impact of the various purposed arrangements of fibers within the mat. Drug release ...

In this paper, we present a first model carried out with COMSOL Multiphysics to model bread baking, considering heat and mass transfer coupled with the phenomenon of swelling. This model predicts the pressures, temperatures and water contents evolutions in the dough for different energy requests. First results obtained are analyzed according to various physical parameters in order to better ...

Study of neurons plays a key role in the fields of basic and medical research aiming at the development of electrically active implants. The Fitzhugh-Nagumo equations are used to model and simulate the spike generation and propagation in a squid giant axon using COMSOL Multiphysics® 3.5a Software. It is shown that the Fitzhugh-Nagumo equations allow for a geometrical explanation of important ...
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques

Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection sensitivity may not be sufficient when the size of the detection target is in nanoscale. To change this, we use ...

The prediction of the exact location and intensity of the electric field induced in the human brain during Transcranial magnetic stimulation is a nontrivial computational task. Numerical simulations of the procedure can be used to acquire first approximations in a safe and controlled environment. In order to make this approach more accessible, it is necessary to reduce computation time as much as ...

We present an optimized and efficient design of an electrohydrodynamic (EHD) micropump for high performance in microscale and biological applications. We are targeting two major applications, a parylene C design for electrically-actuated medicine delivery, and a silicon-based pump design for on-chip cooling of microprocessors and SOCs. The EHD micropump works on the movement of microscale ...

The consequences of hip fracture and femoral fracture are widely known. The mechanical strength of the femur varies in every person, but it is possible to predict the mechanical resistance with parameters like density, dimensions and mineral content. This paper uses different models and empirical studies to determine the mechanical properties of the human femur, developing isotropic and ...

This project utilizes the heat transfer module of the COMSOL Multiphysics environment to model the effects that an ohmic heating probe will have on neural tissue. The model quantifies the thermal impact of active components embedded on a neural micro probe by solving the Penne’s bioheat equation with an external MATLAB function to determine the heat generation along the length of the probe. ...
