This study investigates the dynamics of water wicking in porous media, using Whatman filter paper (grade 1) as a model substrate. Both experimental and numerical approaches were employed to explore influence orientation (vertical horizontal) geometric variations (rectangular trapezoidal shapes) on process. Capillary rise experiments compared with predictions from modified Lucas–Washburn COMSOL simulations. A key advancement is refined theoretical framework extending Darcy's law include...
Abstract We report an experimental study of evaporation two configurations layered porous media that are heated from above by infrared (IR) radiation having ~1,000 W/m 2 intensity. used nearly monodisperse glass beads in each the layers. The (1) coarse and fine beads, stacked side (2) over (FoC). IR heater mimics natural process soils, aim is to study, using three diagnostic tools, how layering affects process, compare it with homogeneous medium case. For experiment we use diagnostics...
The authors present a novel strategy for enhancing conformality in chemical vapor deposition (CVD) based on the concept of growth inhibition. In Part I, they showed how surface site blocking was responsible increase observed at higher pressures high pressure precursors. this work, apply to enhance by considering secondary species that acts as an inhibitor precursor. experimental results obtained TiB2 from Ti(BH4)3dme (dme=dimethoxyethane), with dme acting inhibitor, agree well models, first...
AbstractAbstractThe ignition resistance of AZ91 alloy is investigated during continuous heating experiments and when held at constant temperature in the semisolid range. It found that heating, takes place close to liquidus a significant amount liquid present. Similarly, occurs an isothermal hold region, but after incubation time depends on temperature. Resistance burning closely related high oxidation, which particularly complex case this alloy. The non-protective nature oxides together with...
We measure evaporation rates from water kept in an insulated tank and which is at a temperature higher than the ambient. Different schemes are used to obtain different profiles layer: a) heated bellow, b) left cool after being heated, c) above with IR heater, d) very shallow tank. The idea of having these check role side convection on rates. In cases unstable stratification causes convection; case we have stable stratification, d), uniform layer. heating-from-above experiments simulate some...
This paper presents an axisymmetric problem of two-dimensional finite hollow cylinder with the fractional order derivative 0<α≤2 occupying space D={(x,y,z)∈R3:a≤r≤b,−h≤z≤h}. Convection boundary conditions are applied on curved surface and heat sources generated as a linear function temperature. The analytical solution for temperature, displacement, thermal stresses obtained applying Marchi-Zgrablich, Marchi-Fasulo, Laplace transform technique. Some numerical results temperature change stress...
Evaporation from a porous medium goes through three different stages; the physics of drying is completely in each stage. In first stage, liquid films maintain high hydraulic conductivity leading to evaporation rates; it mainly depends on atmospheric demand. Duration stage 1 given terms suitable length scale, Lcap, which originates competition between capillary, gravitational, and viscous forces. It known that Lcap strongly particle size distribution pore sizes medium. We report experiments...
Heat transfer in flows created by buoyancy, or natural convection, is a widely studied topic across various disciplines spanning as well those with engineering applications. The convective heat rate on surface commonly represented the Nusselt number (Nu), ratio of to diffusive transport, expressed often RanPrm, where Ra Rayleigh number, buoyancy forcing parameter, and Pr Prandtl number. Motivated observation that n∼1/3 for turbulent which implies flux independent length scale (L,...
Current human pluripotent stem cell-derived kidney organoids contain nephron-like structures that lack organotypic patterning. It is thought during development, nephrons form their proximal-distal axial polarity in response to collecting duct-derived signals are absent organoids. To delineate how nephron polarities establish, we profiled development by spatial transcriptomic approaches. Our analyses describe a new the and demonstrate develops adjacent transcriptional boundary duct where...
