N2  - In this study, laminar natural convection heat transfer and fluid flow in a triangular cavity filled with Cu-water nanofluids is studied numerically by using finite volume method. Bottom wall of the cavity is taken as adiabatic while inclined walls have different temperature which are isothermally heated. As governing parameters, Grashof number is taken in the range of 104- 106, the solid particle volume fraction values are taken as 0, 0.02 and 0.04. In the calculation, different viscosity models such as Batchelor, Brinkman, Pak and Cho, Einstein and Maiga et al. are tested on natural convection heat transfer and fluid flow. It is observed that heat transfer increases almost linearly with increasing of solid volume fraction and Grashof number. Also, another finding is that the higest heat transfer is observed when Batchelor model is used.
