Research

The Advanced Fluid Flow Research Group (AFFRG) operates at the cutting edge of mechanical and aerospace engineering, integrating complex numerical simulations with experimental validation to solve real-world challenges. Our research is built upon five strategic pillars that span from fundamental biomimicry to sustainable industrial applications.

Bio-inspired Aerodynamics & Hydrodynamics

This field translates biological adaptations from marine and avian life into innovative engineering solutions. By analyzing the underwater locomotion of penguins and the specific morphologies of their wings, we enhance the performance of micro-air vehicles (MAVs) and underwater gliders (UWGs). Our work on corrugated airfoils and fin designs focuses on developing passive flow control devices that mirror nature's efficiency.

Computational Fluid Dynamics (CFD) & Simulation

Utilizing high-fidelity numerical modeling to solve complex fluid-multibody coupling and thermal-fluid problems. The group employs advanced simulation techniques, such as Detached Eddy Simulation (DES), to evaluate aerodynamic drag reduction for automotive vehicles and stability in aerospace structures. This work serves as the foundational virtual laboratory for validating all biomimetic designs.

Sustainable Energy Systems & Waste-to-Asset Conversion

A core pillar dedicated to addressing the global energy crisis through renewable sources and circular economy practices. Research projects include evaluating the feasibility of solar PV and wind energy systems in the context of Bangladesh. Additionally, the group explores innovative "Waste to Energy" technologies, such as converting plastic and E-waste into useful energy assets through pyrolysis and anaerobic digestion.

Advanced Thermal Systems & Food Preservation

Focused on optimizing energy-intensive industrial processes, particularly in the food industry. The research includes designing low-cost, innovative food dryers that utilize waste heat and hybrid geothermal-solar energy sources. By analyzing moisture-water interaction and heat flux during drying, the group aims to develop zero-energy-based preservation systems for developing nations.

Acoustic Engineering & Noise Mitigation in Fluid Machinery

Investigating methods to reduce the environmental impact of fluid machinery, with a particular focus on wind turbine noise. This research integrates mechanical and aerodynamic perspectives to compare noise reduction techniques, such as biomimetic blade modifications inspired by humpback whale flippers. The goal is to maximize energy harvesting while minimizing hearing risks and environmental disruption.
