Finite Element Analysis of Electro Discharge Machining process

H.Singh [1], Dr. Y.M Puri [1],
[1] Visvesvaraya National Institute of Technology, Nagpur, Maharashtra, India

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 ... Read More

Upscaling of Heterogeneous Rock Properties via a Multiscale Image to Simulation Approach

S. Zhang[1], M. Pal[2], P. Barthelemy[1], M. Lei[1]

[1] 郑州大学化工与能源学院热能系统节能技术与装备教育部工程研究中心

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。 Read More

Modeling the Behavior of a Composite Riser

C. V. Amaechi [1], J. Ye [1],
[1] Lancaster University, Lancaster, United Kingdom

Currently, there are approximately 3,400 deepwater wells in the Gulf of Mexico (GoM) having depths greater than 150 meters, and a worldwide undiscovered deepwater reserves estimated to exceed 200 billion barrels and 25% of the total US reserves (BOEM, 2016), while others are in regions ...

Simulation of Constant-Volume Droplet Generators for Parallelization Purposes

D. Conchouso [1], A. Arevalo [1], D. Castro [1], Y. Ying [1], I. G. Foulds [2]
[1] King Abdullah University of Science and Technology, Thuwal, Makkah, Saudi Arabia
[2] School of Engineering, University of British Columbia - Okanagan, Vancouver, BC, Canada

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 ... Read More

Benchmark Comparison of Natural Convection in a Tall Cavity

H. Dillon[1]
[1]Department of Mechanical Engineering, University of Washington, Seattle, Washington, USA

A comparison of the commercial code COMSOL is performed with the bench-mark solutions provided by the literature for a tall, differentially heated rectangular cavity for aspect ratios of 8, 15, 20, and 33. At small Rayleigh numbers the flow is dominated by conduction. As the Rayleigh ... Read More
