The system integrates multi-effect distillation through thermal vapor compression (MED-TVC), solar flat plate collectors (FPCs), and photovoltaic panels (PVs). The objective function was to minimize the annual cost of the system. To achieve this, an evolutionary algorithm was employed to determine the optimal values of 34 design parameters. The design parameters considered for optimization included the capacity of the gas turbine as the prime mover, electrical chiller capacity, absorption chiller capacity, size of the boiler, partial loads of the gas turbine for each month of the year (12 values in total), number of FPCs and PVs, number of effects in the desalination unit, driving steam pressure, feed water flow rate, driving steam flow rate, and electric cooling ratio. A novel approach was introduced by incorporating a variable electrical cooling ratio, which represents the proportion of electrical and absorption chiller usage, for each month of the year. The optimization aimed to fulfill the heating, cooling, electricity, and freshwater requirements of a residential complex situated in Bandar Abbas, Hormozgan Province, Iran. The optimization results were compared with a constant electrical cooling ratio system where the electrical cooling ratio was assumed to be fixed throughout the year. The optimal scenario, considering the variable electrical cooling ratio strategy, yielded an annual cost of $0.9780 × 10<sup>6</sup> $/year, indicating a significant 10.11% improvement compared to the conventional case ($1.0882 × 10<sup>6</sup> $/year).

By comparing the M-NCS with the microchannel with a fixed cross section (M-FCS), it is deduced that under the same internal volume of the pipe and the same average flow velocity at the inlet, the internal flow rate of M-NCS is greater than that of M-FCS, with a local maximum increase of 43%, which can improve heat exchange efficiency. The Darcy friction factor of the internal fluid of M-NCS is smaller than that of M-FCS. The internal fluid pressure drop of the M-NCS is more significant, which requires a higher external pump energy required. It is also deduced that the average temperature change of the fluid inside M-NCS is larger than that inside M-FCS. In addition, the Nusselt number and convective heat transfer coefficient of the fluid inside M-NCS are larger than those of inside M-FCS. Moreover, the local maximum value of M-NCS is 18.5% higher than that of M-FCS. In summary, the obtained results show that, compared with M-FCS, M-NCS can improve the heat exchange degree and heat diffusion capacity of the fluid inside the microchannel pipe under the same inlet mass flow rate, allowing to enhance the heat transfer.

This research presents a comparative examination of tri-nanomaterial Darcy-Forchheimer flow, involving Oldroyd-B, Maxwell, and Jeffrey (OMJ) nanofluids, over a permeable stretching sheet. The analysis integrates the influences of quadratic thermal radiation, activation energy, magnetic field, and heat source. Additionally, Buongiorno’s model has been utilized along with convective thermal boundary conditions. By leveraging local non-similar approach (LNSA), the modelled highly nonlinear partial differential equations (PDEs) are transformed into a set of ordinary differential equations (ODEs) which are further solved using the finite-difference-based <i>bvp5c</i> solver. It is determined that a rise in the Forchheimer parameter reduces the velocity field. The least and highest temperature profile is observed for Maxwell and Oldroyd-B nanofluids, respectively. It is further noted that per-unit increase in the Forchheimer parameter declines the drag coefficient by 15.43%, 23.87%, and 14.49% for Oldroyd-B, Maxwell, and Jeffrey nanofluid, respectively.
