Abstract Nanofluids, which are suspensions of metallic or ceramic nanoparticle fillers in a variety of liquids, are a new category of heat-transfer fluids. Owing to the changes in thermal conductivity caused by nanofillers, they have thermal properties that are superior to those of conventional fluids; this leads to a more efficient heat transfer, making them attractive for various industrial applications. Using numerical models to support in situ experiments is necessary to analyze nanofluids’ thermal properties and flow; creating a test ring has been suggested to describe the characteristics

Abstract Dynamic fluids have a stationary flow, where the volume of fluid flowing in each cross-section of the pipe in a specific time interval is the same even though the pipe is widening or narrowing but the fluid velocity is different. When a fluid moves through a section where the velocity and height above the surface change, the pressure in the fluid changes. Understanding led to errors in understanding the concept, so this research was carried out to identify the profile of misconceptions in a dynamic fluid material.

Abstract:
In our earlier work, test equipment has been designed, simulated and fabricated to perform experiment on MR fluids in squeeze mode. Preliminary results were gathered and presented for the purpose of validating the test equipment. Therefore, in this paper, a further systematic investigation of MR fluids in squeeze mode has been carried out. As a result, MR fluids experienced rheological changes in three stages during compression and tension. Fluid-particles separation phenomenon was the main caused for the unique behaviour of MR fluids. Particle chains depended on the structure transformation i

Abstract:
In this study, a new three-fluid volume of fluid framework is presented in order to be used as a tool for providing physical insight—in a unified manner—to cavitating sprays and other complex multi-fluid, multiphase fluid flows. The framework accounts for phase change across a sharp interface between two fluids (gas and liquid) including miscibility between the fluid generated due to phase change (liquid vapor due to cavitation in the investigated cases) and one of the existent fluids (gaseous air). Systematic validation of the framework was performed over three cases. The first case is a bubb

Abstract A test apparatus is designed to carry out dynamic and static fluid-loss tests of fracturing fluids. This test apparatus simulates the pressure difference, temperature, rate of shear, duration of shear, and fluid-flow pattern expected under fracture conditions. For a typical crosslinked fracturing fluid, experimental results indicate that fluid loss values can be a function of temperature, pressure differential, rate of shear, and degree of non-Newtonian behavior of the fracturing fluid. A mathematical development demonstrates that the fracturing-fluid coefficient and filter-cake coeff

Two samples of synthetic fluids were formulated from each of deionized WEFGM, ordinary WEFGM and deionized water as base-fluids at two composition (5 and 10%vol) levels of selected additives.

Abstract:
Introduction: Postoperative nausea and vomiting, known as Postoperative Nausea Vomiting (PONV), is one of the problems often experienced by post-operative patients. Most anesthetic drugs have a vasodilation effect which causes hypotension and hypoperfusion, thereby stimulating the CTZ to produce nausea and vomiting reactions. Hypotension will be more dangerous if the body's fluid needs are not met at the time of surgery. Hypotension is one of the triggers that can cause nausea and vomiting. Giving fluids to preoperative patients is generally done to prevent intraoperative hypotension. Methods:

The use of lubricants and hydraulic fluids of both mineral and synthetic origin in agricultural processes could have a deep impact on the environment as a result of their possible dispersion in the ground and aquifers. Replacing them with bio-based fluids, developed to provide good tribological properties and high biodegradability, could contribute to reducing their negative effects. The evaluation of the capacity of such innovative fluids to replace the conventional ones is based on work cycles lasting as long as their lifetime, during which their characteristics must prove to be at least equ
