The governing equations are solved by using the finite volume method based on simple algorithm. The effect of solid nanoparticles on the heat transfer is investigated after comparing our results with experimental data. The founding results showed that the use of nanofluid has enhanced the heat transfer in comparison with pure fluid, and the increasing of Al2O3 concentration enhances the thermal and dynamic parameters. Nusselt number and friction coefficient have been enhanced with the increasing of Reynolds number. This work contributes to ameliorate the cooling systems by integrating the nanofluids in the next generation of microchannels heat sinks.

which make them the core of many applications in several fields, many studies has been done to investigate
their mechanical proprieties since their discovery. In this paper, the free vibration of a single walled carbon
nanotube is studied in an elastic environment based on the theory of non-local elasticity and discretized by
differential quadrature method (DQM); the effect of the surrounding medium on fundamental frequencies is
discussed.

Fundamental natural frequencies and mode shapes of the SWCNT are computed by using a semi-analytical procedure called differential quadrature method (DQM), which gives accurate results in reference with the exact solution.

In order to enhance heat transfer, it is proposed to add cross sections with semi-circular and triangular shapes. Adding these, sections directly influence on the thermophysical parameters of flow.
The following figure shows the geometry of our problem, two microchannels heat sinks with cross section changment in the middle are studied, and compared with simple microchannel heat sinks.

Systems based on gas turbines are suited for cogeneration or combined cycles, making them very efficient and cost-effective.
