ABOUT

The APSYS lab is located at 001 ground floor of Annex Building in the Aerospace Engineering Department, IIT Kharagpur, India. Research on high speed propulsion, pulse jet ignition, vortex combustion, thermoacoustics, spark ignition, jet deflection, etc is being conducted experimentally and computationally. The group performs flow imaging, flow diagnostics, pressure measurements on scaled down test objects. Members have access to a super-computing facility for running computer codes like Fluent, SU2, OpenFoam etc. The Lab has a dedicated compressed air facility, a direct connect modular flow facility capable of running various aerothermodynamic studies. A team of PhD students, MTech students and Undergrad students work on various projects.



NEWS AND ANNOUNCEMENTS

APSYS Labs receives DST funding for turbulent combustion research. The funding will cover equipment procurement for pressure measurements and the purchase of specialty gases used in the tests.

 

General Information

Research Areas

Areas of research include combustion oscillations, vortex driven flows, pulsating flows, method of characteristics, combustion sciences etc.As part of our work in high speed combustors, we are studying flame behavior, ignition, stabilization, flashback and mode transition in high speed combustors both with cavity assisted and strut assisted flame stabilization mechanisms. As part of our work on Combustion Instability prediction and control, we are also looking at vortex driven resonant combustion in Gas Turbine combustors. Active combustion control using secondary injection targeting q' oscillation tailoring are being attempted.

🚀 Just returned from the Aviation Forum 2024, and what an incredible experience it was! I am grateful to my supervisor,  Dr. Amardip Ghosh, for his consistent support and insightful advice, and many thanks to my institute, the Indian Institute of Technology Kharagpur, India, for the financial support that made this journey possible. 🙏

What happens in Vegas doesn’t stay in Vegas – it’s coming with me as newfound knowledge and inspiration for my future work! ✈️

I had the pleasure of presenting my paper titled "Effect of Wall Divergence on the Flow Field Inside a Scramjet Engine" (DOI: 10.2514/6.2024-3891). Engaging with fellow researchers and exchanging ideas has truly been inspiring. The conference was a fantastic opportunity to connect with some brilliant minds in the field of aerodynamics and propulsion.

I’m also deeply thankful to my co-authors for their dedication and hard work in ensuring we met the submission deadline. Your contribution was key to our success. A special thanks to Dipesh Raj, a fellow researcher, for his invaluable help in planning and organizing everything – we couldn't have done it without you!

Looking forward to applying these experiences and insights as I continue the journey in aviation research! ✈️

%Here's a MATLAB code that performs Independent Component Analysis (ICA) on a video sequence. The goal is to treat each frame as a data %vector and then extract statistically independent components from this set using ICA.

%This is particularly useful for motion segmentation, source separation, or background subtraction tasks.

 

% ICA on a video sequence
clc; clear; close all;

% Load video
videoFile = 'your_video.mp4'; % Change to your video file
v = VideoReader(videoFile);
numFrames = floor(v.Duration * v.FrameRate);

% Read first frame to get dimensions
frame = readFrame(v);
grayFrame = rgb2gray(frame);
[rows, cols] = size(grayFrame);
frameSize = rows * cols;

% Reset video to the beginning
v.CurrentTime = 0;

% Construct data matrix: each column is a vectorized frame
dataMatrix = zeros(frameSize, numFrames);
frameCount = 0;

while hasFrame(v)
frame = readFrame(v);
grayFrame = rgb2gray(frame);
grayFrame = im2double(grayFrame); % Normalize to [0,1]
frameCount = frameCount 1;
