We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental evaluations of the detection principle and are in the stage of optimization of several parts of the system. As ...

The effect of the infinite length approximation on evaluating the temperature of the surface of Borehole Heat Exchangers is determined by means of COMSOL Multiphysics. In detail, two 2D models of a BHE are compared: in the first model, the domain is represented by a cross-section of the geometry, while in the second model, it is represented by an axial-section of the geometry and, thus, the BHE ...

A MEMS based Knudsen’s pressure gauge working in the range of 1e-5 mbar to 10 mbar is designed and simulated in COMSOL. The working principle is based on Knudsen’s forces that arise when two plates are held at different temperatures and their separation is comparable to the mean free path of the ambient gas molecules. The forces change the separation between the plates and capacitance between ...

A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail and the final results presented. These include chromium concentration profiles along the column and its ...

One of the main mechanisms in the secondary oil migration from the source rock into oil traps is gravity driven countercurrent imbibition. Many mathematical models describe countercurrent imbibition considering local equilibrium. However, Barenblatt proposed a model to describe the effect of non-equilibrium in oil water displacement. Here, the proposed model was implemented in a gravity driven ...

During the past decade reverse engineering has become a common and acceptable practice utilized by many aftermarket suppliers, and even original equipment manufacturers (OEM). This presentation focuses on the applications of multiphysics software such as COMSOL and Simpleware® in reinventing the design details and manufacturing processes of an existing part in the absence of the original design ...

Cryotherapy and thermotherapy are common methods of treatment for acute injuries ranging from ankle sprains to complex surgery. The idea behind such treatment is that a change in temperature will reduce pain and constrict fluctuations in blood flow at the targeted area. The purpose of this study is to simulate the vascularized tissue reaction and the resulting blood flow fluctuation from thermal ...

The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against both the humerus and the radius. The cause remains unknown, but prior studies suggest joint incongruency as an ...

The high temperature measurement of thermal conductivity is vital for predicting nuclear fuel performance both during reactor operation and accident conditions. The proposed method uses experimental thermograms obtained via high temperature laser-flash heating of a disc-shaped sample in combination with finite element analysis and parameter optimization to calculate the thermal conductivity ...

The Life+ GreenWoolF project is aimed at demonstrating that green hydrolysis with superheated water is an effective way to convert wool wastes into organic nitrogen fertilizers. The core of the process is represented by the reaction tank (Figure 1) in which the hydrolyses reaction takes place. The temperature of the material during the reaction is one of the most influencing parameter and has to ...
