Thermal Performance of Diffusion Bonded Compact Heat Exchangers using Al2O3 Water Nanofluid

The value of compact heat exchangers CHEs has been recognised in aerospace, automotive, gas turbine power station, and other industries for the last 50 years or more. This is attributed to many reasons, for example manufacturing restrictions, often high efficiency requirements, low cost, and the use of air or gas as one of the fluids in the exchanger. Together with new and improved forms of CHEs, these advances are an excellent opportunity to bring compact heat exchangers into the process industry, particularly where saving energy is an essential target. High energy prices are also encouraging companies to use energy saving strategies at their plants as much as possible. During decades, attempts to increase heat transfer, decrease heat transfer times and eventually improve energy efficiency have been made. Recent advancements in nanotechnology have facilitated the creation of a new type of liquids called nanofluids. Most theoretical and computational experiments have shown that nanofluids demonstrate an improved coefficient of heat transfer relative to their base fluid. This CFD research explores the impact on the performance of straight square compact heat exchangers from Al2O3 water nanofluid flow. The Al2O3 water nanofluids with three weight fractions of nanoparticles i.e. 0.4, 0.8, and 1.2 percent were used. The effect of nanofluid were measured and observed to influence the heat transfer and flow of fluids in a straight square compact heat exchanger. The following conclusions can be drawn based on the provided results, the thermal conductance are approximately 29 higher and the heat transfer are approximately 35 higher in comparison with the conventional fluid i.e. water.

Determination of Range of Splash of Testing Fluid during Hydro Testing of Knife Gate Valve

There are certain trivial experimental findings which may not have a major significance but their execution is considered to be of such a nature as to complete the study in the specified area. Likewise in the field of hydro testing of valves and flow equipment, there is a basic requirement of operation of the same under influence of applied hydro pressure. This is required to determine the performance parameters like the thrust and the torque required to operate the equipment. While doing so, in addition to the qualitative requirements, an additional requirement of space has to be considered to ensure the surrounding area is not affected due to splashes of the testing fluid while under pressure. This paper shall consider such a case for hydro testing of a knife gate valve. At a given pressure, when the door or gate of the valve is initiated to open, there is an initial splash of testing fluid which ejects out of the orifice created due to the opening. The horizontal range of this splash shall be mathematically determined. An experimental finding shall then be presented to confirm the derived formulae. A conclusion shall be drawn thereafter dictating the percentage error and the employability of the derived formulae.
