A mechanistic model for inhaled airborne transmission of Smallpox
A mechanistic model for inhaled airborne transmission of Smallpox
Airborne pathogen transmission requires a deeper understanding of fluid dynamics in respiratory droplets. Using large eddy simulation, this study analyzes the airflow and pathogen-bearing aerosol trajectories in realistic upper airway geometries, focusing on smallpox due to its transmissibility and available data. The mechanics-guided model integrates virological and epidemiological factors, providing infection exposure durations and offering potential for modeling other viruses like Mpox.
Develop a CFD informed theoretical model to predict plasma and solute transport in a wide rang of tumor microenvironment
Develop a CFD informed theoretical model to predict plasma and solute transport in a wide rang of tumor microenvironment
The primary aim of this research is to develop a theoretical model that predicts plasma transport and solute uptake within solid tumors. This model integrates the Diffusion-Reverse Advection (DRA) framework with Computational Fluid Dynamics (CFD) simulations to capture the complex dynamics of biofluid transport in tumor tissues. By focusing on the theoretical aspects, this approach seeks to offer a computationally efficient and biologically relevant tool for simulating tumor perfusion.
Localized vortices significantly impact particle transport in the upper respiratory tract, and their effects can be estimated using a 2D potential flow model with point vortices. The reduced-order model aligns well with full-scale simulations, demonstrating how vorticity and particle size influence transport in both healthy and distorted airways.

Industrial Tank Cleaning System
Industrial Tank Cleaning System
Rescue Robot ( A Solidwork Design Project )
Rescue Robot ( A Solidwork Design Project )
An automated tank cleaning system involves a pump that fills the tank to a specified water level and then stops automatically. After the water is used, the cleaning system activates and, once cleaning is complete, the pump resumes filling the tank.
Working on this project enhanced my understanding of pump mechanisms, Arduino programming, water sensor functionality, and long nut bolt mechanisms.
During building or structure collapses caused by earthquakes or fires, rescue robots are often essential. Together with some classmates, I designed a rescue robot for this purpose. This robot can navigate uneven terrain, carry sufficient food and oxygen for trapped individuals, and break through small obstacles using its arm. This was my first Solidworks project, and I learned many valuable skills, such as precise measurement, accurate assembly, and design criteria.

Design and Build a U-Type Shell and Tube Heat exchanger
Ansys Introductory Project
Ansys Introductory Project
Designed and built a U-type shell and tube heat exchanger. It was a project assigned by the Mechanical Department of BUET. It is designed to decrease approximately 25 degrees of temperature. It is more efficient than a normal shell and tube heat exchanger. This project improved my design criteria knowledge and helped to realize the difference between a designed model and a real model.
It was an introductory project assigned by our department. Ansys was quite new for us then. We were asked to design a rectangular shape containing a hole and do a stress analysis on it. It was a quite simple work to be done. But as it was our first project, we were excited lot to work on this simulation software.
Undergraduate Thesis: Increase Efficiency of a wind turbine imposing a nozzle in front of it
Undergraduate Thesis: Increase Efficiency of a wind turbine imposing a nozzle in front of it
Our main concern is to increase the efficiency of a wind turbine. So, we planned to insert a nozzle shape in front of the turbine blade which will increase the velocity of wind more effectively than before.
We select Chattogram area in Bangladesh as our plot. Normally we can get power from a wind turbine for 4/5 months of a year whereas using nozzle we can get power constantly all over a year which will make a great impact in power generation of our country.
