The paper reports a new method for three-dimensional observation of the location of focused particle streams along both the depth and width of the channel cross-section in spiral inertial microfluidic systems. The results confirm that particles are focused near the top and bottom walls of the microchannel cross-section, revealing clear insights on the focusing and separation mechanism. Based on...

The shipping volume in inland waterways has been rapidly increasing recent years. However, it is still challenging to trace oil spills caused by maritime accidents. In this study, the spill dispersion trajectory rivers was obtained simulating of particles under different waterway conditions based on a simulated flow field. Firstly, field using fluid (VOF) model and solution an open-channel equa...

Many authors analyzed triangular and trapezoidal approximation of fuzzy numbers. But, to best of our knowledge, there is no method for symmetric trapezoidal fuzzy number approximation of fuzzy numbers. So, in this paper, we try to convert any fuzzy number into symmetric trapezoidal fuzzy number by using metric distance. This approximation helps us to avoid the computational complexity in the pr...

Surface acoustic wave (SAW) excitation of an acoustic field in a trapezoidal glass microfluidic channel for particle manipulation in continuous flow has been demonstrated. A unidirectional interdigital transducer (IDT) on a Y-cut Z-propagation lithium niobate (LiNbO3) substrate was used to excite a surface acoustic wave at approximately 35 MHz. An SU8 layer was used for adhesive bonding of the ...

A new apparatus has been constructed to investigate the quenching of laminar hydrocarbon-air flames, at elevated initial pressures. The pressure-tight quenching channel is of trapezoidal form, with very smooth decrease of the channel width along its one meter length that is almost equivalent to a parallel-plate flame arrester. Propane-air mixture has been tested on the entire flammability domai...

Canals are major water conveyance systems used to deliver water to irrigation fields. Due to wide variability of local soil conditions, the stability of designed channel section may not be ensured while implementing the optimal canal sections in the real field. Hence, incorporation of slope stability condition is very helpful to provide stable irrigation channels. This paper presents Particle S...

Abstract This paper considers a dual-channel supply chain with one vendor and multiple buyers in which (1) channel is an offline where standard products are produced shipped to the (2) second online flow of customized between buyers/consumers. The first follows managed inventory consignment stock (VMI-CS) agreement buyers. lead time buyer considered controllable, at cost. Two models analyzed: m...
