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 ...

An implementation of the Electrical Impedance Tomography (EIT) forward problem in a generalist FEM package is presented. It fulfils the complete electrode model boundary conditions, combining current injection with contact impedance on a single boundary. Our implementation is benchmarked with the EIDORS FEM library. The Comsol Multiphysics environment proves consistent and provides a flexible ...

A biconcave-shaped Red Blood Cell was trapped and deformed in a dual-trap optical tweezers. The two highly focused trapping beams of Gaussian intensity distribution were modeled as background field in the COMSOL Radio Frequency Module. The 3D radiation stress distribution on the cell surface was computed via the Maxwell stress tensor. The 3D deformation of the cell was computed with the ...

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 ...

Retinitis Pigmentosa (RP) and Age-related Macular Degeneration (AMD) are diseases causing blindness in a large number of people. In this type of degenerative disease, mostly the photoreceptors are damaged. Thus attempts have been made to electrically stimulate the surviving inner retinal neurons and retinal ganglion cells (RGC) in order to restore vision. In this paper, the electrode-tissue ...

This work enunciates the principles of SAW design from a physical perspective, examining the standard engineering modelling assumptions in some detail. An integral form analytical expression based on 2D elastic isotropic theory is validated against a COMSOL Multiphysics® simulation, corresponding to the traditional COM approach. Next, a COMSOL model of the full 3D problem, including anisotropy, ...
