The impedance tube is commonly used to characterize sound absorbing material. In order to obtain reliable results, the sample must fit perfectly into the cross section of the tube. In practice, this often results in a minimal gap between the sample and the wall of the tube. A narrow gap ... Read More

In the field of laser applications, surface treatment is highly studied. Two process categories are commonly used. First processes use very short pulses (femto or pico seconds) known to avoid thermal effects and to have high spatial resolutions. Second processes have higher interaction ... Read More

Microreactors have gained popularity in fuel production industry. This is due to its high surface area to volume ratio, enhanced mass and heat transfer, short residence time and a more sustainable practice. The catalytic hydrodeoxygenation (HDO) reaction of 4-Propylguaiacol (4PG) to 4 ... Read More

Ice flows because at low stresses it deforms viscously; the viscosity depends upon the stress. The lubrication approximation (LA) states shear stress is proportional to the product of the ice depth and surface slope. At ice divides the slope and shear stress are zero meaning the ... Read More

The COMSOL Multiphysics® Multibody Dynamics Module was used to analyze the performance of a high-speed metal forming press consisting of multiple processes for preform of aluminum blanks. The objective was to redesign the drive mechanism of the press, changing from a 4 bar linkage ... Read More

Many industrial applications require special treatments for fluid products, such as: deagglomeration, dispersion, homogenization, emulsion, special mixing or even catalysis of chemical reactions. Such effects can be obtained through cavitation in a closed ultrasonic reactor, in which it ... Read More

Small-scale short-term thermal energy storage (TES) systems and large-scale seasonal TES systems have been the focus of many research projects. However, large-scale short-term TES units have not been covered in great depth, even though they play an important role by decoupling the heat ... Read More

Microalgae biomass is an essential part of the global ecosystem. Not only is it responsible for 50% of the global oxygen but also proved to be useful in the development of organic polymers, antioxidants, pharmaceuticals, and feedstocks for aquatic animals. It is considered as an ... Read More

In this work, we present a methodology for the design and analysis of a double-sided linear induction motor for a scaled Hyperloop pod in COMSOL Multiphysics®. The key aspects are discussed as follows: Formulation of problem and simulation environment: The goal is to design a Double ... Read More

Single droplet drying (SDD) is an established experimental set up in which an isolated droplet is dried under a controlled environment. The drying behavior in the SDD experiments is often complicated and challenged to observe. Hence, a robust model of single droplet drying can provide an ... Read More
