Food dehydration processes assisted by high-power ultrasound (HPU) have become an efficient technology with a great potential in its implementation. To produce the desired effects in the samples, it is necessary that the dehydration system, composed by a HPU transducer and an ultrasonic ... En savoir plus
In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be ... En savoir plus
MEMS gyroscope technology provides cost- effective method for improving directional estimation and overall accuracy in the navigation systems. This paper presents a tuning- fork gyroscope (TFG) [1] with a perforated proof mass. The perforated proof mass used in the design enables the ... En savoir plus
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 ... En savoir plus
Modern wind turbine blades consist of composite airfoil shaped structures that form a hollow acoustic cavity. Because of continually varying aerodynamic forces, gravitational loads, lightning strikes, and weather conditions, all blades will experience leading and trailing edge splits, ... En savoir plus
Among optical gas sensing methods, photoacoustic (PA) spectroscopy combined with a laser source has proven to be a very robust and sensitive method for trace gas detection. COMSOL Multiphysics® software was used to calculate the frequency response of differential Helmholtz resonator ... En savoir plus
Surface coating can fullfil their function satisfactorily over an extended period of time only if there is a good bond between the concrete substrate and the coating. The most numerous cases of blistering affect the airtight covers of the concrete subjected to negative pressures of ... En savoir plus
This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric ... En savoir plus
Micro-power generators (MPGs) harvest and store small amounts of ambient energy. The motivation of this paper is to compare the MPG modeling and simulation results obtained from COMSOL Multiphysics® with those obtained using three other approaches: CoventorWare®, ANSYS® and ... En savoir plus
A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into ... En savoir plus
