In this article, an elaborated evaluation has been presented for the stratified MHD Jeffrey nanofluid flow towards a stretching surface in the presence of gyrotactic micro-organisms. The analysis of the flow by taking into consideration the viscous dissipation, Brownian motion, Joule heating and thermophoresis and the assumption of thermal, solutal and motile density stratification aspects. The governing nonlinear system of partial differential equations (PDEs), administering the flow, are turned to a group of the nonlinear ordinary differential equations (ODEs) via using an appropriate similarity transformation and later solved numerically by implementing the Keller-box approach with the help of algebraic software Matlab. The impacts of a variety of parameters on the fluid motion, heat, mass, density of the motile micro-organisms, local skin friction, local Nusselt number, local Sherwood number and local density number of the motile micro-organisms are examined with the aid of graphs as well as tables. The results suggest that the motile micro-organisms density is a decreasing function of the bioconvection Lewis number, bioconvection Pecket number and microorganisms concentration difference. The Sherwood number and density rate of motile micro-organisms are bigger in the case of magnetic parameter and Lewis number.

Considering the excellent transport performance of treelike networks and the effect of roughness on fluid flow in a microchannel, the present work studied the optimization of a symmetric treelike roughened network with minimum hydraulic resistance under constant total channel base volume. It was found that there is an optimal base diameter ratio βm of channels at two successive branching levels that minimizes the hydraulic resistance of the network. The βm value increases with increasing average roughness height. A larger βm value is needed to minimize the hydraulic resistance of the network with larger branching number N, branching level m, and channel length ratio γ, because the increases in N, m, and γ reduce the channel diameter and magnify the influence of roughness on the fluid flow.

Matrix nanocomposites are high performance materials possessing unusual features along with unique design possibilities. Due to extraordinary thermophysical characteristic contained by these matrix nanocomposites materials they are useful in several areas ranging from packaging to biomedical applications. Being an environment friendly, utilization of nanocomposites offer new technological opportunities for several sectors of aerospace, automotive, electronics and biotechnology. In this regards, current pagination is devoted to analyze thermal features of viscous fluid flow between orthogonally rotating disks with inclusion of metallic matrix nanocomposite (MMNC) and ceramic matrix nanocomposites (CMNC) materials. Morphological aspects of these nanomaterials on flow and heat transfer characteristics has been investigated on hybrid viscous fluid flow. Mathematical structuring of problem along with empirical relations for nanocomposites materials are formulated in the form of partial differential equations and later on converted into ordinary differential expressions by using suitable variables. Solution of constructed coupled differential system is found by collaboration of Runge–Kutta and shooting methods. Variation in skin friction coefficient at lower and upper walls of disks along with measurement about heat transfer rate are calculated against governing physical parameters. Impact of flow concerning variables on axial, radial components of velocity and temperature distribution are also evaluated. Contour plots are also drawn to explore heat and thermal profiles. Comparison and critical analysis of MMNc and CMNc have been presented at lower and upper porous disks. Our computed analysis indicates that hybrid nanofluids show significant influence as compared to simple nanofluids with the permutation of the different shape factors.
