The concept of immiscible displacement as an invasion percolation (IP) process driven by heat and mass transfer is used in a pore network model for convective drying of capillary porous media. The coupling between heat and mass transfer occurs at the liquid-gas interface through temperature dependent equilibrium vapour pressure, surface tension and phase change enthalpy (in evaporation and cond...

This study presents a method for the experimental determination of local volumetric mass transfer coefficient kLaL in high-pressure two-phase flow water (H2O) and carbon dioxide (CO2) micro-capillary using colorimetric method. H2O CO2 are fed continuously co-axially injected at (10 MPa) moderate temperature (303 K) into microcapillary. Under conditions studied, segmented is formed. The dissolve...

Abstract In this work, a hybrid sensor based on silica capillary in balloon-like shape for simultaneous measurement of displacement and temperature is proposed the first time, to best our knowledge. The fabricated by splicing segment hollow core fiber between two single mode fibers (SMF) bending balloon with at top-center position. transmission scheme, SMF-capillary-SMF configuration excites an...

Background and Objective: Short Tandem Repeats (STR) show considerable differences among individuals in the population from which they used for identification. There are various methods for analysis of these STR loci, and capillary electrophoresis method already used as an international standard. Due to the high costs of this process, this study aimed to set up a Multiplex PCR method in some st...

Electrowetting generates flow patterns inside drops when AC voltages are employed. For AC frequencies around the drop eigenfrequency (typically O(1kHz) or less), capillary waves emanate from the contact line giving rise to a net motion in the bulk of the drop. This flow can be described by a capillary wave-driven Stokes drift. At higher AC frequencies (above 10kHz, depending on liquid conductiv...

A capillary microfluidics-integrated sensor system is developed for rapid assembly of bionanoreceptor interfaces on-chip and label-free biosensing. Genetically engineered Tobacco mosaic virus (TMV) virus-like particles (VLPs), displaying thousands copies of identical receptor peptides FLAG-tags, are utilized as nanoceptors for antibody sensing. Controlled and accelerated assembly of VLP recepto...

A simple capillary electrophoretic method based on 1-phenyl-3-methyl-5-pyrazolon (PMP) derivatization has been developed for simultaneous separation and determination of nine aldoses (xylose, arabinose, glucose, rhamnose, fucose, galactose, mannose, glucuronic acid and galacturonic acid). The separation of PMP-labeled monosaccharide derivatives was carried out in uncoated capillary (48.5 cm x 7...

Experimental investigation was done to find the role of capillary tube length and amount of refrigerant charge on the overall heat transfer coefficient in condenser and evaporator and actual COP of a simple vapour compression refrigeration system. It was concluded that increasing of the refrigerant charge in the system largely enhances the overall heat transfer coefficient in the evaporator by ...

A fundamental 2-D model was developed to predict the heat and mass transfer that occur during the frying and cooling process of tortilla chips. Semi-empirical correlations were included to account for structural changes, such as shrinkage and expansion due to puffing. All water present in the tortilla chip was considered bound and led to shrinkage when removed. The parameters that were studied ...

This study compares the performance characteristics of a household refrigerator equipped with an Electronic Expansion Valve (EEV) with those with a capillary tube. A 513-liter top-mount refrigerator, originally equipped with a capillary tube, was retrofitted with a Pulse Width Modulated (PWM) expansion valve and extensively tested. Comparative analyses were performed based on standardized pull-...
