Abstract

nIn the industrial application hydraulic lifts have a variety of applications on a massive scale. As the energy resources required for the operation are relatively high as compared to the output provided by lifts, there is an alarming rate to optimize the process. So, to bridge the gap we have come up with an innovative and exclusive fabrication of the hydraulic lift systems based on the use of Composite Fluids for the operation. This will eventually lead to the energy conservation at the input level with high performance rate and output. To maintain the same displacement at output by reducing the input effort of the hydraulic system compared to existing hydraulic system by using a ‘Non-Uniform Composite Fluid’ by employing the thermal effects on it as well.n

Keywords: Hydraulic lift, composite fluid application, energy conservation, thermal application, numerical analysis

nAbstract

At present time, accumulated theoretical material of the studies of the equilibrium forms of the gas bubbles or mercury drops, fixed on the surface of solid material in the fluid or on the glass bottom of vessel with fluid, under the acceleration of gravity change, was carried out either on the basis of geometric similarity laws that greatly simplify the essence of physical processes, or on the basis of theoretical qualitative estimates of the existing hydrostatic equations of fluid equilibrium, taking into account a decrease of the acceleration of gravity, without carrying out a numerical solution of these equations. The theoretical and experimental study of the behavior of gas bubbles, fixed on the surface of solid material in the fluid, under the acceleration of gravity change was carried out by Shoikhedbrod with great computer accuracy and experimentally confirmed during flight tests aboard of the IL-76K flying laboratory. The paper presents the application of previously obtained results for modeling of the behavior of a drop of mercury, fixed on the glass bottom of vessel with fluid, under the acceleration of gravity change. The conducted computer modeling of the behavior of a drop of mercury, fixed on the glass bottom of vessel with fluid, under the acceleration of gravity decrease, experimentally proved during the process of the carried out tests aboard of the flying laboratory (FL) IL-76K, showed the practical use of the developed computer model both for the simulation of the behavior of real gas bubbles and mercury drops in the fluid in one vessel of the wide range of Bond numbers (β) in the chemically-technological processes occurring in the main control systems of the operability of automatic spacecraft, in real conditions of microgravity.

nAbstract

In this short report, a brief review on surface-driven microfluidic flow is provided. Also, the maskless lithography and indirect bonding technique are used to fabricate a single SU-8 based glass microfluidic device. Dyed ethylene glycol is prepared as working liquid to test the fabricated device. The surface-driven microfluidic flow of dyed ethylene glycol is recorded by a CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second. This short report may be useful in future to control the working liquid inside the microfluidic lab-on-a-chip system. Liquid-microflow is slower at higher surface-area to volume ratio inside the microchannel. The surface-to-volume ratio is generally very high inside any Nanochannel. Therefore, the Liquid-flow may be stopped before the Nanochannel. Hence, only gas-Nanoflow may happen inside the Nanochannel producing the subject of Nanofluidics. Hence, this short report may be useful in future to control the working gas inside the nanofluidic lab-on-a-chip system.

n Special Issue Descriptionn

Fluid pressure gradients, buoyancy effects, and permeability distribution control the flow paths in hydrothermal systems between metal sources and areas of ore deposition. The role that deformation processes and fluid pressures play in generating and maintaining permeability within active faults, shear zones, associated fracture networks, and various other structures at all crustal levels is a major source of structural controls on ore formation in many epigenetic systems. Pore connection is poor in hydrothermal systems with low intergranular porosity, and fluid flow is typically governed by fracture permeability. On continents, close to convergent plate boundaries, as well as on the ocean floor, close to mid-ocean ridges, there are strong heat fluxes that give rise to hydrothermal systems. Three essential elements are necessary for their formation: fluids, heat, and the ability of fluids to move through rocks. The majority of mineral deposits, which originated by direct crystallization in cracks and gaps within the rocks or by replacement of pre-existing rocks, were deposited by hydrothermal fluids associated with the cooling of shallow intrusive bodies. Seawater undergoes modifications as a result of interactions with heat and the earth’s crust, giving rise to hydrothermal fluid. At hydrothermal vents on the seafloor, these liquids emit and then return to the ocean’s water.

n Special Issue Descriptionn

The way fluids behave when passing through a porous medium, such as a sponge or wood, or when filtering water through sand or another porous substance, is known as fluid flow through porous media. As is frequently seen, some fluid passes through the media while the majority of the fluid is trapped in its pores. Traditional theories of flow in porous media make assumptions about the homogeneity, isotropy, and pore structure of the medium. Single-phase steady-state flow, multi-well interference, oil-water two-phase flow, natural gas flow, elastic energy-driven flow, oil-gas two-phase flow, and gas-water two-phase flow are common flow problems in porous media. To express the capillary force or fluid velocity as a function of different other factors, such as the effective pore radius, liquid viscosity, or permeability, Darcy’s law and the principle of mass conservation are combined. A substance that consists of a solid matrix and an interconnected void is referred to as a porous medium. We assume that the solid matrix either exhibits minor deformation or is rigid (which is the typical scenario).

n Special Issue Descriptionn

A Newtonian fluid is one in which the local strain rate, or the rate of change of its deformation over time, is linearly connected to the viscous stresses resulting from its flow at every place. The rate at which the fluid’s velocity vector changes determines how much stress is there. Only when the tensors describing the viscous stress and strain rate are coupled by a constant viscosity tensor that is independent of the stress state and flow velocity can a fluid be said to be Newtonian. The viscosity tensor is reduced to two real coefficients, which describe the fluid’s resistance to continuous shear deformation and continuous compression or expansion, respectively, if the fluid is also isotropic (mechanical properties are the same in any direction). A fluid that deviates from Newton’s law of viscosity—constant viscosity regardless of stress—is said to be non-Newtonian. When subjected to force, the viscosity of non-Newtonian fluids can change, becoming either more liquid or more solid. For instance, ketchup is a non-Newtonian fluid because shaking causes it to become runnier. Most frequently, the viscosity of non-Newtonian fluids depends on the shear rate or shear rate history (the progressive deformation caused by shear or tensile stresses). Nevertheless, some non-Newtonian fluids with shear-independent viscosities continue to display typical stress-difference patterns or other non-Newtonian behaviors. In a Newtonian fluid, the coefficient of viscosity serves as the proportionality constant, and the relationship between the shear stress and shear rate is linear, passing through the origin.
