Recently, remarkable developments have taken place, leading to significant improvements in microfluidic methods to capture subtle biological effects down to single cells. As microfluidic devices are getting sophisticated, design optimization through experimentations is becoming more challenging. As a result, numerical simulations have contributed to this trend by offering a better understanding of cellular microenvironments hydrodynamics and optimizing the functionality of the current/emerging designs. The need for new marketable designs with advantageous hydrodynamics invokes easier access to efficient as well as time-conservative numerical simulations to provide screening over cellular microenvironments, and to emulate physiological conditions with high accuracy. Therefore, an excerpt overview on how each numerical methodology and associated handling software works, and how they differ in handling underlying hydrodynamic of lab-on-chip microfluidic is crucial. These numerical means rely on molecular and continuum levels of numerical simulations. The current review aims to serve as a guideline for researchers in this area by presenting a comprehensive characterization of various relevant simulation techniques.

Entropy Generation and Consequences of MHD in Darcy–Forchheimer Nanofluid Flow Bounded by Non-Linearly Stretching Surface

Present communication aims to inspect the entropy optimization, heat and mass transport in Darcy-Forchheimer nanofluid flow surrounded by a non-linearly stretching surface. Navier-Stokes model based governing equations for non-Newtonian nanofluids having symmetric components in various terms are considered. Non-linear stretching is assumed to be the driving force whereas influence of thermal radiation, Brownian diffusion, dissipation and thermophoresis is considered. Importantly, entropy optimization is performed using second law of thermodynamics. Governing problems are converted into nonlinear ordinary problems (ODEs) using suitably adjusted transformations. RK-45 based built-in shooting mechanism is used to solve the problems. Final outcomes are plotted graphically. In addition to velocity, temperature, concentration and Bejan number, the stream lines, contour graphs and density graphs have been prepared. For their industrial and engineering importance, results for wall-drag force, heat flux (Nusselt) rate and mass flux (Sherwood) rate are also given in tabular data form. Outputs indicate that velocity reduces for Forchheimer number as well as for the porosity factor. However, a rise is noted in temperature distribution for elevated values of thermal radiation. Entropy optimization shows enhancement for larger values of temperature difference ratio. Skin-friction enhances for all relevant parameters involved in momentum equation.Symmetry 2020, 12, 652 2 of 23 in base liquid for a shorter period of time, the achieved results are more effective than using a simple base fluid. This formulated mixture is known as nanofluid. These mixtures have enormous applications in engineering, industry and advanced nanotechnology. The manufacturing procedures at micro-level industries, nuclear reactors and power engines are directly related to these formulations. Petroleum industry, chemical industry, geothermal industry, and other related fields are important in this context. The pioneer study on this formulation has been reported by Choi [1]. The process of heat transport had shown much improvement after involvement of nanofluids. In particular, the dramatic effect is noted in power engines, refrigerators, nuclear reactors, fuel cells, thermal management, etc. For example, Chamkha and Khaled [2] reported some similarity solutions of mixed convection and heat transfer in Darcy medium. Parvin and Chamkha [3] disclosed features of odd-shaped cavity filled with nanofluid.

A theoretical study is conducted to examine the peristaltic pumping with double-diffusive convection in Jeffery nanofluids through a two-dimensional infinite asymmetric channel. The flow is examined in a wave casing of orientation that moves pace with the velocity of the wave. The peristaltic wave train on the walls that have different amplitude and phase is chosen to form channel irregularity. Rosseland approximation is noticed in the modeling of the transmission radiation heat transfer and temperatures of the walls are recognized constants. The replica has a great impact in discovering nanofluid dynamic influences on peristaltic motion, in biological vessels as symbolized by transportation of heat in blood flow, food molecules, hormones, novel pharmacodynamics pumps, and engineered gastrointestinal motility enhancement. Peristaltic motion has applications in physiology, such as transport of urine, transport of food bolus through gastrointestinal tract, and transport of blood through small blood vessels. Analytical results have been established for stream function, axial velocity, temperature, and absorption and nanoparticle volume fraction. The effect of the principal hydrodynamic parameters (thermophoresis, Brownian motion, Dufour, and Soret) and Grashof numbers (concentration, thermal, nanoparticle) on peristaltic transport patterns with double-diffusive convection are deliberated with the support of computational outcomes found. The pictorial investigation is done to investigate the possessions of miscellaneous limitations on flow quantities of curiosity.Base fluids have lower thermal conductivities than nanometer-sized particles for which it is very higher. Nanofluids play a major role in improving thermal conductivities. Further, nanofluids are used in power generation, drug delivery, cancer therapy, etc. In addition to that, magneto-nanofluids have interesting applications in most fields. Choi and Eastman 1 found the improvement of heat transfer routine of the ordinary fluids with the help of metallic nanoparticles by dramatically increasing the thermal conductivities.Buongiorno 2 provided a template for circular motion in nanofluids, and, keen on that, Brownian diffusion and thermomigration are the significant slip mechanisms. Albeit such improvements in the works, the non-Newtonian fluids have added a great deal of responsiveness in many industrial and engineering applications. As a supplement study, the Navier-Stokes equations are not apt to present the flow of non-Newtonian fluids. Various communications are analyzed in the collective works to predict the characteristics of such fluids and one of the materials is Jeffrey material 3 that considers time derivatives, whereas non-Newtonian fluid mechanics assumes convective derivatives.The suspensions of small sized (1-100 nm) metallic particles into a base fluid results in the formation of nanofluids. The blending of strong particles into base liquids like water, motor oil, ethylene glycol (EG), and so on, makes these liquids. The structure of nanopartic...
