In this work, the mass transport properties of a neutral solute in rough microtube with porous wall under combined influence both pressure and electric fields for non-Newtonian power-law fluids are examined. This investigation explores effect various roughness patterns, such as sinusoidal, triangular, rectangular, well different flow behavior indices, on behavior. The Poisson–Boltzmann equation, Cauchy momentum species conservation equation were solved computationally profiles to assess...

Modal and non-modal stability analyses are performed for Poiseuille flow of a Bingham fluid overlying an anisotropic inhomogeneous porous layer saturated with the same fluid. In case modal analysis, resultant Orr–Sommerfeld type eigenvalue problem is formulated solved via Chebyshev collocation method, using QZ decomposition. It found that no unstable eigenvalues present problem, indicating linearly stable. Therefore, analysis attempted in order to observe short-time response. For initial...
A number of microfluidic systems interest essentially consist micro-scaled channels/tubes, whose walls are inherently rough. The novelty the current study lies in exploring impact wall roughness on mass transfer case flow through a microtube with porous wall. investigation is possibly first attempt at effect for porous-walled, rough microtube, as earlier studies were limited to analysis hydrodynamic and thermal effects only an impervious microtube. In particular, corrugation amplitude...
In this study, both modal and non-modal stability analyses are attempted in case of Couette–Poiseuille flow a Bingham fluid overlying porous layer. Such configuration is widely encountered the geophysical context oil drilling. The solution problem yields no unstable eigenvalue, similar to viscoplastic non-porous channel configuration. Thus, analysis performed throw light on short-time characteristics. primary goal unveil complex interplay between upper plate velocity (Couette component)...
Abstract Eleven edible wild greens of West Bengal ( Enhydra fluctuans, Hydrocotyle asiatica, Herpestis monneira, Oxalis corniculata, Mollugo spergula, hirta, Cephalandra indica, Hygrophila spinosa, Amaranthus spinosus, Rumex vesicarius and Trianthema monogyna ) were analysed for moisture, protein, fat, carbohydrate, ash, crude fibre, calcium, phosphorus, iron, nicotinic acid, ascorbic acid calories. The nutritive value the leaves these species was generally low.
The present study is undertaken to analyze the hydrodynamic stability of pressure-driven flow non-Newtonian fluid-porous systems, where fluid exhibits power-law rheology. Such combined systems are widely prevalent in diverse geophysical and industrial applications. In beginning, modal analysis has been performed for comprehending long-time transition characteristics. plots eigenfunctions corresponding critical eigenmodes demonstrate intricate interplay between viscosity (quantified by...
Occurrence, coverage and chemical constituents of aquatic flora were studied in two Indian ponds over a period 39-month order to gain an insight into their associations infestation for implications conservation management. Species diversity was recorded presence invasive species (Alternanthera philoxeroides (Martius) Griseb. Lemna aequinoctialis Welwitsch). These should be managed view beneficial uses. Nymphaea pubescens Willd, threatened species, recorded. Positive association Nymphoides...
The role of the transition layer (existing at fluid-porous interface) on hydrodynamic stability a channel configuration has been investigated, particularly in context non-Newtonian (power-law) fluid. inherent relationships among layer, velocity discontinuity interface, and flow criticality are explored detail. Unlike shear-thickening, effect shear-thinning behavior is found to be non-monotonic, owing an intricate interplay between fluid rheology. Possible avenues exploit these...
The depectinization kinetics of bael (<italic>Aegle marmelos</italic>) juice using the enzyme pectinase was evaluated and it observed to follow Michaelis–Menten model.
