: SIMULATION OF SOLAR BASED COLD STORAGE FOR FRUITS AND VEGETABLES at CTARA, IITB

- The energy demand and greenhouse gas emission of traditional cold storage leads to global warming. The cooling process of the room is properly carried out in the purpose to ensure high quality and safety of products. This study examined a room with a surface of 35×29×17 (ft) and a well-insulated chamber and examined the heat exchange from the side surfaces and ceiling. Heat and mass transfer in cold rooms is a complex phenomenon because of the presence of the air flow and the coupling between heat transfer and airflow. Temperature, velocity, humidity and heat transfer coefficient measurements were carried out in a ventilated cold room filled with fruits and vegetables. This Project also aims of designing a stacking system for onion which takes care of all aspects. Engineering tools and methodologies has been used first to evaluate the proposed design and analysis the areas of improvement in it to reach the goal of cost effective and user-friendly staking system for onion for medium (50 MT) to large scale (100 MT) onion storage systems. CFD analysis for the staking system have been carried out for the cold room in which stacking system is to be stored. 

: Design, Development and Simulation of Electric Ambu-Lifts for Airport Application at Nandan GSE

- Ambu-Lift is a kind of a special-purpose vehicle with airport specific application to attend, lower down, lift, and transport patients and disabled persons from ground to aircraft deck and contrariwise easily in normal as well as emergency conditions. These ambu-lifts operate on diesel chassis and thus have harmful exhaust gas emissions, high noise and lower fuel economy as well as higher maintenance for their operations. The project e-Ambulift demonstrates the electrification of an Ambulift right from design, simulation and experimentation. in this e-Ambulift project, a simulation model for the electric vehicle has been created in matlab simulink software wherein the input parameters are fed into the model for the required output results that are necessary for the e-ambulift. The created simulink model is firstly verified with the results from other papers published in reputed journals. The results of simulation from matlab simulink model for defined parameters are compared with the results obtained by experimentation / testing of the real- world Electric Ambu-Lift developed from the same defined inputs. Various output parameters like total energy consumption, vehicle speed, battery voltage, current, State of Charge (SOC) and distance(range) are evaluated from simulation and compared with experimental results for self-defined drive cycle and input parameters in this project. The results are also obtained on simulation model for various available drive cycles. This project also includes the effect of regenerative braking and auxiliary loads on the output parameters. The project concludes with the comparative analysis of the electric ambu-lift with more aspects of future work in this domain.
