Tissue engineering (TE) is a multidisciplinary field involving principles of engineering and life sciences to improve the health and quality of life by repairing, restoring, maintaining, or enhancing tissue and organ function using cells, scaffolds, and growth factors alone or in combination. There are several artificial tissues that are already being used which include fabricated skin, ...

Mathematical skin models play an important role in fields such as transdermal drug delivery and assessment of dermal exposure to industrial chemicals. Extensive research has been conducted on modeling skin for transdermal drug delivery; however, little effort has been made to view the skin as a permeable layer to expel waste chemicals or toxins from the body. In this work, we focused on topical ...

A 2D mathematical model of coupled heat and mass transfer describing oven roasting of meat was formulated from first principles. The current formulation of model equations incorporates the effect of shrinkage phenomena and water holding capacity. The model equations are based on conservation of mass and energy. The pressure driven transport of water in meat is expressed using Darcy’s equation. ...

In this work we have constructed a 2D COMSOL model for the drying of Latex. It is based on a prior 1D model of Kiil, but also includes the effects of a flowing air stream, which is necessary to remove the evaporated water vapor. The model illustrates several features of drying that are not accessible to the 1D model, in particular the a profile in the air/water interface that forms near the ...

Optimal storage of carbon dioxide (CO2) in aquifers requires dissolution in the aqueous phase. Transfer of CO2 from the gas phase to the aqueous phase or oil phase would be slow if it were only driven by diffusion. Dissolution of CO2 in brine (oil) forms a mixture that is denser than the original brine. This causes a local density increase, which induces natural convection currents accelerating ...

A mathematical model is developed to determine the weight loss and the freezing rate during the freezing of unwrapped foodstuffs. The model allows comparing two freezing processes; the first uses nitrogen gas at -80°C and the second uses cold air. The model includes thermophysical properties that are temperature dependent to take into account the ice formation. The time step has to be chosen ...

The heat and mass transfer processes occurring in a domestic oven is in detailed analyzed in this work, with the final objective of improving the global energy efficiency of the system. A 3D Finite Element model developed with a Multi-physics approach is validated with the experimental data from the standard test for energy consumption of the European Union (EN 50304:2001). In this test a brick ...

The optimization of operating conditions in multitube membrane modules is highly complex. The multiple physics and irregular geometries involved create a challenge for predicting their behavior. This work analyzes the performance of H2 purification through a module containing seven membranes. Using experimental parameters, a 3-D model was devised, specifying the membrane as a reacting boundary ...

It is necessary to understand and control nanopore behavior in order to develop biosensors for a variety of applications including DNA sequencing. The fluidics of nanopore devices we fabricated exhibits a range of interesting phenomena, such as enhanced conductance and current rectification. By electrically biasing nanopores, we were able to actively control the nanopore conductance in real time ...
