This study presents the design, fabrication and characterization of a piston-driven shock tube, a compact and low-cost device designed to produce supersonic flow. The study uses a high-frequency Data Acquisition(DAQ) system comprised of NI X Series USB 6341. The electronics system measures pressure voltage from the transducer, amplifies it, and sends the output to the DAQ system for visualization in LabVIEW. The study utilizes ToF method with a 100 mm transducer spacing for the velocity measurement. A maximum shockwave mach number upto 1.723 was achieved using 0.072mm aluminum diaphragm at maximum burst pressure ratio of 14.239, characterized by x/l ratio. Schlieren imaging is used to visualize the shockwave and flow patterns behind it.Item MODEL PREDICTIVE CONTROL-BASED OPTIMAL TRAJECTORY TRACKING IN AUTONOMOUS QUADROTOR SYSTEM(I.O.E, 2024-03) Simkhada, Dipesh; Bhatta, Hemant; Karki, Krishna Bahadur; Thapa, Prasanna Pratap; Luitel, Mahesh ChandraOptimal trajectory tracking through nonlinear optimization is a computational process that aims to track the reference path for a system, considering the dynamics and objectives of system along with the constraints that are provided. Among current approaches in trajectory tracking formulation as an optimization problem, this paper describes Model Predictive Control( MPC), an approach that provides a continually evolving optimized trajectory tracking system that also respects system dynamics and constraints. The project showcases both the numerical simulation for the MPC implemented for reference trajectory tracking followed by an implementation on the actual quadcopter. However, in the actual hardware implementation flight test have been conducted in the quadrotor where only the attitude has been controlled in the PX4 firmware directly using Model Predictive Control. In this paper, the MPC-based control technique is used for trajectory tracking of the quadrotor model in different types of trajectories. For numerical simulation, non linear model has been developed and analyzed using the Finite-length time horizon control referred to as Model Predictive Control whereas, for SITL(Software-in-The-Loop) simulation, linear model of MPC have been used. For the flight test, to achieve efficient computational cost for the Pixhawk Flight Controller, the linear model has been implemented to analyze the attitude control shown by the quadrotor system.Item Experimental Analysis on Vapour Compression Refrigeration System(I.O.E, 2024-04) Shrestha, Jeena; Thapa, Niraj; Pradhan, Rejisha; Baniya, Sujit Sah; Amatya, Vishwo PrasadVapour Compression Refrigeration system (VCRs) has been extensively used in Refrigeration and HVAC sectors due to its beneficial characteristics like higher COP and Refrigerating Effect. However, these sectors and consequently VCRs contribute to a substantial and rapidly increasing global energy consumption which has raised huge concerns. This project aimed to experimentally analyse the vapour compression refrigeration system and compare performance of the system with and without heat addition. It was conducted by fabricating a VCR unit and adding extra heat to the unit before and after the compression process. The COP of the system increased by 46.07% when heat was added before compressor while the current consumption of the compressor decreased by 12.07%. However, COP of the system decreased by 22.7% when heat was added to the system after compressor with 32.6% increase in current consumption.
