This study investigates magnetohydrodynamic mixed convective heat transport within a rotating cylinder-equipped enclosure. It employs finite element analysis to explore a range of parameters' effects on heat transfer, including magnetic field strength, Richardson number, Reynolds number, and cylinder diameter. The study reveals that Nusselt number decreases with increased magnetic field and Richardson number, while heat transfer increases with rising Reynolds number and larger cylinder diameter. Additionally, the rotation direction of the cylinder (clockwise or counterclockwise) proves to be significant in various scenarios.

The objective of this approach is to design a cooling system for achieving a cooling effect sufficient to maintain operating temperature of an electronic component. The temperature is controlled and optimized by tuning the system for P, PI and PID controller configurations. The investigation is conducted for the optimum value of the gains that results in the fastest response time and a stable system.

The study conducts a three-dimensional numerical simulation of shell-and-tube heat exchangers with continuous helical baffles (STHXsHB). CAD model was developed and simulated using finite element method (FEM) in ANSYS. The results demonstrated that STHXsHB outperforms conventional STHXs with significantly higher heat transfer coefficient per unit pressure drop (72-127% higher) and lower shell-side pressure drop (59-63% lower) for the same shell-side mass flow rate. The computational model is validated by comparing shell-side average Nusselt number with experimental results.

The project aims to develop a comprehensive driver drowsiness detection and speed control system to enhance road safety and prevent accidents caused by driver fatigue or distractions. The system relies on head motion analysis to identify signs of drowsiness, and a prototype of the speed control mechanism is implemented using DC motors. An integrated alarming system will notify the driver in real-time if drowsiness or distraction is detected. By reducing the vehicle's speed when signs of drowsiness are identified, the system effectively mitigates potential hazards. Furthermore, the system also has the capability to detect driver distraction, ensuring proactive safety measures based on head position data collected through a devised head mount. This project holds the potential to significantly contribute to the reduction of road accidents and safeguard the well-being of both drivers and passengers.
