Experimental Study of Drying/Evaporation in an Effective 2D Porous Medium

Yiotis A.G., Tsimpanogiannis I.N., Stubos A.K., National Center for Scientific Research “Demokritos”, GR

Liquid-to-gas phase change, where the mass transfer that drives the process occurs in the gas phase, and the subsequent growth of the produced gas phase within a porous medium, is involved in a wide variety [...]

Computational Microfluidics for Miniaturised Bio-Diagnostics Devices using the code “TransAT”

Narayanan C., Lakehal D., ASCOMP GmbH, CH

We will report on our recent advances made in predicting this class of flows with our CMFD code TransAT (www.ascomp.ch), using the Level Set approach as an “Interface Tracking Method”. Our code incorporate phase-change capabilities, [...]

Numerical Investigation of Phase-Changing Heat Transfer for Laser-Assisted Direct Nano Imprint Processing

Hsiao F-B, Wang D-B, Jen C-P, Lee Y-C, Chuang C-H, National Cheng Kung University, TW

Laser-Assisted Direct Imprinting (LADI), a novel and promising technique, has been proposed since 2002 to utilize an excimer laser to irradiate and heat the silicon surface through a highly-transparent quartz mold preloaded onto the silicon. [...]
