A parabolic trough solar collector is an advanced concentrated solar power technology that significantly captures radiant energy. Solar power will help different sectors reach their energy needs in areas where traditional fuels are in use. This study aims to examine the sensitivity analysis for optimizing the heat transfer and entropy generation in the Jeffrey magnetohydrodynamic hybrid nanofluid flow under the influence of motile gyrotactic microorganisms with solar radiation in the parabolic trough solar collectors. The influences of viscous dissipation and Ohmic heating are also considered in this investigation.

Governing partial differential equations are derived via boundary layer assumptions and nondimensionalized with the help of suitable similarity transformations. The resulting higher-order coupled ordinary differential equations are numerically investigated using the Runga-Kutta fourth-order numerical approach with the shooting technique in the computational MATLAB tool.

The numerical outcomes of influential parameters are presented graphically for velocity, temperature, entropy generation, Bejan number, drag coefficient and Nusselt number. It is observed that escalating the values of melting heat parameter and the Prandl number enhances the Nusselt number, while reverse effect is observed with an enhancement in the magnetic field parameter and bioconvection Lewis number. Increasing the magnetic field and bioconvection diffusion parameter improves the entropy and Bejan number.

Nanotechnology has captured the interest of researchers due to its engrossing performance and wide range of applications in heat transfer and solar energy storage. There are numerous advantages of hybrid nanofluids over traditional heat transfer fluids. In addition, the upswing suspension of the motile gyrotactic microorganisms improves the hybrid nanofluid stability, enhancing the performance of the solar collector. The use of solar energy reduces the industry’s dependency on fossil fuels.

This chapter aims to present the context, the approach and the pedagogical tools deployed at École Centrale Marseille (ECM) to promote gender equality in engineering education. The ECM has put several mechanisms in place such as challenging traditional gender stereotypes, social representation of the engineering profession and facing the realities of a professional world that is overwhelmingly masculine, including awareness of the glass ceiling effect on access to positions of responsibility and prevention of sexual harassment. The ECM model combines multidisciplinary studies with a professional grounding with the aim of educating students to be able to transform society. In 1997, the ECM founded the Mediterranean Network of Engineering Schools with the main goal of fostering sustainable development in the Mediterranean basin. The ECM has been part of the community of practice on gender equality initiated by Mediterranean Network of Engineering Schools through its participation in the H2020 TARGET project on gender equality in research and higher education.
