Abstract. Nanofluid are categorized under class of fluids that have extreme potential to enhance the heat transfer in heat exchangers. However, the interaction between the exchanger and the ambient (heat leak) is an essential issue since it could deteriorate the exchanger performance. The quantity of the heat loss is directly related to the temperature of the hot fluid, the Reynolds number, and the type and volume fraction of the nanoparticle. The experimental study presents the heat leak when distilled water is mixed with different concentration of Al2O3 (range from 1% to 3%) and streamed into three different types of heat exchangers, namely concentric, shell and tube, and plate type. The results emphasize that presence of nanoparticles improves the Nusselt number (convection coefficient) and the NTU number (exchanger performance). The analysis also shows that heat leak factor augments with the increase in VoF of nanofluid in all types. However, plate type exchanger has the lowest losses to the ambient, followed by shell and tube and finally concentric type.
