Actual trends in lightweight construction and safety-relevant technologies cause an increasing demand for reliable design of joining connections. Increasing power density and compact design require dimensioning of joints with low safety factors. Thereby additional security measures are ... En savoir plus
The present research work aims to present thermal analysis of Electrical Discharge machining. During its machining process a large amount of heat is generated due to sparking phenomena, It has been assumed that heat distribution follows the Gaussian Distribution function. As such a ...

To maintain same droplet size across parallel devices, new break-up strategies based on geometry are been studied. In this work, we model a geometrically-set droplet generator, in which the droplet break-up occurs by a block and break mechanism. In other words when the disperse phase ... En savoir plus
The main focus of the present study is the parametric investigation of the influence of viscosity on breakup dynamics of the non-Newtonian sodium carboxymethylcellulose (CMC) droplets. It presents the numerical simulations of the fluid dynamics of CMC droplets with shear-thinning ... En savoir plus
The unique optical properties of plasmon resonances in noble metal nanoparticles have been extensively investigated owing to their ability to enhance the electric field amplitude but also to tailor its spectral and spatial distribution. Among all application domains, nonlinear optics ... En savoir plus
The determination of the constitutive equation of a nonlinear viscoelastic fluid is a challenging task, especially if a space-dependent equation is needed [1]. In this contribution, we present simulations of certain rheometry tests of a high-viscosity nonlinear viscoelastic fluid with a ... En savoir plus
节能、高效、紧凑已经成为制冷空调行业的发展趋势，其中强化换热技术尤为关键。因此，本文采用COMSOL软件对微型错排管换热器进行了建立二维模型，基于瞬态模型，采用流动和传热模块进行有无交变压力波的数值模拟分析。结果发现随着交变压力波的添加大大增加了速度场、压力场及温度场的波动情况，使得管内工质边界层破坏降低了传热的热阻综合空化链式理论，交变压力波能够起到强化传热的作用，提高了制冷效率，有利于推动制冷行业的发展。 En savoir plus
Fin tube heat exchangers are widely used in air conditioning systems. Various fin structures have been proposed and studied in literature to enhance their heat transfer performance. However, enhancement in heat transfer is often accompanied by pressure drop penalty. This study utilized a ... En savoir plus
Uncertainty appears in many aspects of physical simulations including stochastic design parameters, hard-to-specify input distributions, probabilistic boundary and initial conditions, and unknown geometries. Uncertainty Quantification (UQ) has emerged as the science of quantitative ... En savoir plus
