Two-dimensional numerical investigation has been carried out using an in-house CFD code to obtain the heat transfer performance of normal, uni-directional and bi-directional lid-driven cavity. The 2D in-house code is based on single phase approach for studying steady state laminar flows. Pure water (PW), ionic liquid (IL): 1-ethyl-3-methylimidazolium methanesulfonate; [C₂mim][CH₃SO₃], ionic liquid mixtures (PW + IL) and alumina (Al₂O₃) nanoparticle enhanced ionic liquids (NEILS) are used in the present investigation. The thermophysical properties of all the heat transfer fluids used in the present numerical investigation were obtained from the experimentally measured data available in the literature. The obtained results showed that uni-directional lid-driven cavity exhibits 68.78 % higher Nu_avg value at Re = 1900 in comparison with normal lid-driven cavity for pure water. The use of [C₂mim][CH₃SO₃] ionic liquid also enhances the heat transfer performance by exhibiting 115.48 % higher Nu_avg value in comparison with pure water at Re = 1900. Moreover, 15 % wt Al₂O₃ nanoparticles in 0.25PW + 0.75IL gives 21.2 % and 161.16 % higher heat transfer performance in comparison with ionic liquid and pure water respectively at Re = 1900. Furthermore, it is also observed that 10 % wt Al₂O₃ nanoparticles in 0.25PW + 0.75IL shows similar heat transfer performance like ionic liquid at all Re.
