Numerical investigation of heat transfer enhancement of nanofluids in an inclined lid-driven triangular enclosure.

The behavior of nanofluids is investigated numerically in an inclined lid-driven triangular enclosure to gain insight into convective recirculation and flow processes induced by a nanofluid. The present model is developed to examine the behavior of nanofluids taking into account the solid volume fra...
