In order to address the impact of concentration gradients on chemistry – turbulence interaction in turbulent flames, REDIM reduced is constructed incorporating scalar dissipation rate, which a key quantity describing mixing process. This achieved by providing variable gradient estimate evolution equation. such case, tabulated as function coordinates and rate an additional progress variable. The...

Purpose – The purpose of this paper was to study the combined effect of hygro and thermo-mechanical behavior on a plastic encapsulated micro-electro-mechanical systems (MEMS) package during the reflow process after exposed to a humid environment for a prolonged time. Plastic encapsulated electronic packages absorb moisture when they are subjected to humid ambient conditions. Design/methodology/...

This technical note presents a coupled thermo-hydromechanical model for unsaturated soil, which can be applied in the context of high temperature. A new pore gas or bulk air transfer equation is introduced. Additionally the effect of temperature on the latent heat of vapourisation and specific heat capacities is incorporated. Adsorbed water is also included. The performance of the model is demo...

Mixing of miscible liquids is essential for numerous processes in industry and nature. Mixing, i.e. interpenetration of molecules through the liquid/liquid boundary, occurs via interfacial diffusion. Mixing can also involve externally or internally driven hydrodynamic flows, and can lead to deformation or disintegration of the liquid/liquid boundary. At the moment, the mixing dynamics remains p...

The present study considers the numerical examination of an unsteady thermo-solutal mixed convection when the extra mass and heat diffusions, called as Soret and Dufour effects, were not neglected. The numerical simulations were performed in a lid-driven cavity, where the horizontal walls were kept in constant temperatures and concentrations. The vertical walls were well insulated. A finite vol...

The phenomenon of convective flow with heat and mass transfer has been studied extensively due to its applications in various fields. effects nonlinear thermal radiation (NLTR), slip, thermal-diffusion (Soret) diffusion-thermo (Dufour) on magenoto-hydrodynamic (MHD) towards a stretching cylinder the presence triple stratification (TSF) are investigated this paper. governing equations transforme...

Reconfigurable systems, like the field-programmable gate array in electronics, have numerous advantages including cost, adaptability, robustness, and security. Despite this, few other chip-based technologies have developed equivalently ubiquitous reconfiguration methods. As a first step to applying this paradigm to channel-based microfluidics, we present here a rapid optofluidic technique to cr...

There is a growing interest in modulating the temperature under the illumination of light. As a heat source, metal nanoparticles (NPs) have played an important role to pave the way for a new branch of plasmonics, i.e., thermo-plasmonics. While thermo-plasmonics have been well established in photo-thermal therapy, it has received comparatively less attention in materials science and chemistry. H...
