Thermal Regulation in a Cylindrical Cooling System with Discrete Heat Sources
March 2024
This project investigated the thermal management performance of P, PI, and PID controllers in a 3D cylindrical cooling system with discrete thin strips as heat sources via computational fluid dynamics (CFD) based simulation using the COMSOL 6.0 software. The system features a hollow cylinder with four evenly spaced heat sources along its axis, insulated walls, and a central temperature probe providing feedback to maintain a set point. Air enters through a semicircular inlet, with its flow regulated by the controllers, and exits at atmospheric conditions. Using the Galerkin finite element method, the Navier-Stokes and energy equations are solved to analyze steady-state and dynamic responses, evaluating overshoot, rise time, oscillation, offset error, and settling time.
Designing Double Tube Heat Exchanger For Various Industrial Purposes
February 2023
Developed and manufactured a cost-effective, high-performance double-tube heat exchanger (DTHX) designed for a wide range of industrial applications. The system employed a multi-pass parallel flow configuration to maximize thermal exchange between two fluids, ensuring efficient heat transfer. Water was selected as the working fluid, with a copper (Cu) inner tube and a mild steel (MS) outer shell, balancing thermal conductivity, mechanical strength, and material costs. The design and analysis process leveraged advanced engineering tools such as SOLIDWORKS, ANSYS Fluent, and HTRI, enabling precise modeling, computational fluid dynamics (CFD) simulations, and thermal evaluations to optimize both performance and affordability.
Gesture Controlled Mechanical Arm based on Arduino
August 2022
Designed and developed a robotic arm functioning as a Collaborative Robot (Cobot), capable of being operated through human hand gestures. The control system integrated components such as an Arduino UNO microcontroller, servo motors, flex sensors, an Inertial Measurement Unit (IMU), and gyroscopes to ensure responsive and accurate movements. SOLIDWORKS was used to design and analyze the designing factors for the arm. The actual robotic arm was constructed using Polyvinyl Chloride (PVC) board for structural efficiency, the Cobot was engineered with an emphasis on both cost-effectiveness and precision. Its intended applications include assisting in delicate tasks, such as delivering medication tablets to patients, thereby enhancing safety and reducing human intervention in repetitive healthcare processes.
