Aerodynamic performance of a tandem wing configuration inspired from dragonfly gliding flight for MAV application
Rajosik Adak, Arindam Mandal, Sandeep Saha
The design of micro air vehicles (MAVs) introduces aerodynamic performance challenges due to the small size and, consequently, the low Reynolds number 10000-100000. Natural fliers…
Performance enhancement of a 100 watts class Tesla turbine
Arindam Mandal, Rajosik Adak, Sandeep Saha
Tesla turbines are an attractive but less explored area in low-power applications. This article presents an experimental investigation of a centimeter scale Tesla turbine in bi and…
Puff-like instability in laminar to turbulence supercritical transition of round jets
Neelakash Biswas, Aviral Sharma, Sandeep Saha +1
We explore the laminar to turbulence transition of round jets at low Reynolds number (Re < 1000) using a novel experimental setup and linear stability theory (LST). The setup has a…
Investigation of Flight Conditions where Box-Wing Outperforms Mono-Wing Configurations for Small UAVs
Jasmine Jerry Aloor, Bikalpa Bomjan Gurung, Gauri Wadhwa +3
We investigate the aerodynamic efficiency and flight dynamics of mono-wing and box-wing configurations across various parameters, including aspect ratio, velocity, and lift require…
Rotational Instabilities in Stratified Miscible Layers
Saunak Sengupta, Sukhendu Ghosh, Sandeep Saha +1
Instability of stratified multi-phase flow in a rotating platform becomes important because of a potential role in micro-mixing and micro-machines. Centrifugal actuation can play a…
Rotational Instabilities in Microchannel Flows
Saunak Sengupta, Sukhendu Ghosh, Sandeep Saha +1
Mixing in numerous medical and chemical applications, involving overly long microchannels, can be enhanced by inducing flow instabilities. The channel length, is thus shortened in…
