In this paper a thermal electric finite element method (FEM) analysis was used to investigate the thermal properties of individual electrically driven platinum micro-heaters. The geometric optimization for the micro-heater was performed by simulating a wide range of possible geometries ... 詳細を見る
Thermocouples have been used for measurement of temperature ever since the discovery of Seebeck effect. Though the voltage output of a thermocouple is a function of the temperature difference between hot and cold junctions, the response time and the magnitude of voltage depends on the ... 詳細を見る
The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in ... 詳細を見る
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 ... 詳細を見る
The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground ... 詳細を見る
This work deals with the computer simulation of the blood flow, the arterial wall deformation and their 3D bidirectional interaction, including initial stresses and root displacements. The flow is laminar and steady with flexible walls modeled with a hyperelastic Demiray material model. ... 詳細を見る
The actuator comprises of a temperature sensitive composite deflecting beam, a piezoelectric substrate and a field effect transistor. The temperature rise causes an expansion in the composite beam thereby causing it to deflect. The deflecting beam impinges on the piezoelectric crystal ... 詳細を見る
Micro-tweezers have been widely investigated because of their extensive applications in micro-fluidics technology, microsurgery and tissue-engineering. It has been reported that thermal actuation provides greater forces and easier control when compared to electrostatic micro actuation. ... 詳細を見る
This paper presents the design and simulation of high sensitivity and fast response capacitive humidity sensor. Generally, the capacitive humidity sensor is made up of parallel electrode, the upper electrode being a grid with various line width and line spacing. A model is simulated ... 詳細を見る
Conductive Composites such as carbon fiber reinforced composites are increasingly used in safety critical aerospace applications. The catastrophic macro structural failure of composite structures initiates from a micro level failure event such as fiber breaks. The ability to detect ... 詳細を見る
