Projects

Description:

A re-design of a commercially available heat exchanger model for enhanced performance. The primary goal of this project was to enhance heat transfer and reduce pressure drops in the tubes and across the fins by changing the geometry of the fins used and selecting optimal number of tubes and rows, suitable pitches and tube lengths. The goal which was achieved through comparison and fabrication of the designed heat exchanger. Soft-wares such as-  solidworks and Ansys were used to model the heat exchanger which was then fabricated using cheap and available local materials, retaining accuracy and efficiency.

Description:

A remote and contact-less health monitoring system intended to scope out potential Covid-19 infections and provide quick and effective healthcare. The project was designed to bring about a Healthcare Infrastructure which may analyze specific symptoms and make an initial diagnosis regarding the detection of Covid-19 infection and necessary steps to be taken. Implementation was carried out using computer linked Arduino software which collected data from physical sensors for 3 vital signs (temperature, pulse rate, oxygen concentration) and ran the data through an ML model trained using data collected from Bengali ethno-linguistic group and their incurred symptoms due to a Covid-19 infection. The trained model had an accuracy score of 0.9021.

Description:

A solar energy based Cooling Hub as an energy-efficient solution for the fisherman communities in the coastal areas of Bangladesh. Project Jolod aimed to support the overall economic growth of the fishermen in coastal area by proposing a solar energy based cooling hub for reducing the stiffness and lack of monitoring in the cold chain of the fish market. The solution proposed had three major segments of the static and portable type, and the overall power consumption was only from solar energy. 

(The project was crowned champion at the Sustainable Energy Innovation Challenge - Bikiron).
