We call the laminar flow a streamline or viscous flow. In Laminar flow, the fluid flows in parallel layers with lesser lateral mixing and no disruption between the layers. In fluid dynamics, laminar flow is a smooth or regular movement of particles of the fluid. While driving when you encounter a turn on the left or right of the road, the laminar flow becomes a non laminar flow. You can think of the laminar flow of liquid as the straight road (free of turns). These particles have a smooth movement as we walk on a smooth road. In a fluid, for laminar flow, all the particles carry constant attributes like velocity, pressure, and speed. This page discusses laminar fluid flow, lamellar flow, non-laminar flow, lumina flow, and laminar flux in detail. If in this case ants deviate from their path and make two directions, then it is the non-laminar flow. So, don’t you think this is a laminar flow? Yes, that’s true.Ī laminar flow in fluid mechanics is the straight or linear flow of all the particles of the fluid that is similar to the marching of an ant. The successive ants smell this chemical and march-like an army. Consequently, as a heat transfer fluid, nanofluids should be used in either the laminar flow or the fully developed turbulent flow at sufficiently high Re in order to yield enhanced heat transfer performance.You know that an ant releases an invisible, fragrant chemical called Pheromone. The results from this work suggest that the particle-fluid interaction has a significant impact on the flow physics of nanofluids, especially in the transition and turbulent regions. A simple scaling analysis was used to show that these behaviors may be attributed to the variation in the relative size of the nanoparticle with respect to the turbulent microscales at different Re. Three new observations were made for nanofluids in the transition and turbulent regions: (1) The onset of transition to turbulence is delayed (2) both the friction factor and the convective heat transfer coefficient are below those of water at the same Re in the transition flow and (3) once fully developed turbulence is established, the difference in the flow and heat transfer of nanofluids and water will diminish. It was found that in the laminar region, the nanofluids exhibit pronounced entrance region behaviors possibly due to the flattening of the velocity profile caused by the flow-induced particle migration. The Reynolds number (Re) varied from 600 to 4500, covering the laminar, transition, and early fully developed turbulent regions.

The friction factor and convection heat transfer coefficients were measured for nanofluids of various volume concentrations (up to 5%) and were compared with those of the base fluid.

In this work, an experimental investigation was conducted to study single-phase forced convection of Al 2 O 3-water nanofluid in a circular minichannel with a 1.09 mm inner diameter. In spite of the extensive studies in the literature, a consensus is lacking on if and how the dispersed nanoparticles alter the thermal transport in convective flows. Nanofluids have been proposed as a promising candidate for advanced heat transfer fluids in a variety of important engineering applications ranging from energy storage and electronics cooling to thermal processing of materials.
