Usually, when calculating the blood flow in cerebral arteries and intracranial aneurysms, blood is modeled as a Newtonian fluid, neglecting its shear-thinning behavior. Since flow diverting devices slow down the blood flow in the aneurysm sack, the accuracy of this assumption had to be reviewed. A Carreau Yasuda model is introduced as a non-Newtonian model for blood viscosity. CFD simulations of ...

Morphogenesis is a tightly regulated process that has been studied for decades. Previously we developed data-based mechanistic models for a range of developmental processes with a view to integrate the available knowledge and to better understand the underlying regulatory logic. In our previous papers on simulating organogenesis in COMSOL Multiphysics® we discussed methods to efficiently solve ...

When an electronic device is worn for extended periods, possibly in direct contact with human skin, heat must be safely transferred away from the device, without exceeding standards and regulatory temperature limits on the skin and on the exposed surfaces of the device. Heat transfer is dominated by convective heat transfer to the surrounding air (possibly trapped air under clothing), and by ...

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 ...

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 ...

In this presentation, we study the modeling of physiology and muscoskeletal biomechanics using COMSOL. The outline for the presentation is in particular: Why is COMSOL particularly powerful for modeling physiology? Modeling soft tissues like cartilage Optimization to determine soft tissue properties Modeling of moving loads in the TMJ Robust 3D models from imaging data Model of primary ...

Insulin released by the beta-cells of pancreatic islets is the main regulator of glucose homeostasis, hence, insulin secretion models are of considerable interest for many possible applications. Building on our previous oxygen consumption and cell viability model for avascular islets of Langerhans, we developed an exploratory insulin secretion model that couples the hormone production rate to ...

This article describes the design of MEMS based cantilever structure intended for determination of blood group and it is compared with manual method. Cantilever structure design has a sensing layer and when a blood sample comes in contact with this, results in coagulation. The surface tension in turn occurs due to chemical and biological reactions of antigen and antibodies resulting in ...

Silver nanoparticles are valuable in the field of plasmonics since silver has a higher field enhancement factor compared to other metals that possess plasmonic properties. The plasmonic properties of silver nanoparticles can be finely tuned to the incident light wavelength through their size, shape and dielectric environment, and they have long-term stability. In this work, an ultrathin polymer ...

Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique is used for the deposition of high quality biocompatible polymer thin films. During the deposition process the temperature of the laser target should be kept below 193K to assure the proper quality of both evaporation and deposition phases of the process. On a first approach COMSOL Multiphysics® was used to describe and analyze the ...
