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.
