Roles and Reponsibilties:

  1. Involved in developing a new type of Electronic Time Fuze sub-miniature type for missile applications. This involves development of small aperture Pitot tube, pressure valve and a turbofan. The development is still under progress. The designing involves hand-calculations, development of Pitot tube and a turbo- fan coupled to a generator.  Development of Pitot tube is done with the aid of commercially available CFD software i.e. ANSYS (Fluent).Since the Pitot tube has a very small diameter aperture; it is designed by considering the effect of boundary layer and turbulence. K-epsilon model is used to solve for the flow field inside the Pitot tube. It is also interesting to note that there exists cavity flow at the entrance of the Pitot tube and the profile at the entry of the tube matters a lot. Optimum Opening of Pressure Valve for fluid flow to the turbo-fan is calculated with the aid of ANSYS (Fluent) and the MATLAB Code written to solve for the same. Pressure valve opening is simulated in ANSYS (Fluent) using dynamic mesh with the solver being K-ε model.
  2. Involved in the design of mechanisms viz. Missile Support Unit, Rear Stopper Mechanism, Spring Loaded Mechanism, Article Locking Mechanism and Hatch Opening Mechanism, which were mounted within the canister housing. The design process involved hand calculation and analysis of the structure with the aid of NX-NASTRAN being the major part of the design. The effect of the static weight of the missile and the dynamic weight due to momentum of missile during the time of launch were considered for designing the mechanisms. On the other hand the effect of the fumes, during the launch, on the mechanisms was considered and thermal analysis was also carried out.

MSc(Engg) Project:

Project Title: "Attenuation of Shock Wave viscous medium"

Project Guide: Prof. G Jagadeesh (Department of Aeropsace Engineering, Indian Institute of Science, Bangalore)

An attempt was made to understand the mechanism of attenuation of shock wave in liquids. Five liquids of different viscosities were considered for the study. The study demanded an experimental set- up, for which a horizontal diaphragmless type shock generator was designed. The design involved development of a fast actuating valve and a right angle bend to mount the test section. It was found that there was attenuation at the bend, which was analyzed using ANSYS (FLUENT) in order to check out the results obtained experimentally. Whereas, retraction time of the valve was evaluated using MATLAB code, written to solve for the Newton’s Equation. Flow through the valve was analyzed using dynamic meshing in and ANSYS (FLUENT). Different designs were tried to obtain a stronger shock by opening the valve at an order of 1-2ms. Visualization of the retraction speed of the valve using high speed camera was carried out. Though the fast actuating valve performed considerably well, practical difficulty was faced at the right angle bend. Nearly 30% of attenuation in the shock strength was observed across the bend, which paved way for designing a conventional vertical shock tube set-up. It was calibrated before carrying out the experiments for its reliability and was found satisfactory. Experiments were carried out by flush mounting the pressure transducers to the wall of the test section. The signals were recorded for all the five liquids of different viscosities. Each liquid was subjected to shock waves of different strengths and three runs were taken by keeping the shock strength constant to calculate the reliability of the signal. All the signals with error bar  were plotted for each liquid separately and compared. It was observed that maximum attenuation took place at the gas-liquid interface, followed by drastic reduction in the shock strength. The data were taken to calculate the shock speed in liquid and to verify the Tait’s Equation of State. Also an attempt to extend the Tait’s Equation of State to   viscous liquids was carried out. Though the values were found to be considerably close to the experimental values, but it was found deviating at higher pressures. It was concluded with the statement that the attenuation phenomenon depends on viscosity and density. In the meantime, an attempt to analyse the flow using ANSYS (FLUENT) was also carried out to solve the flow field, wherein the attenuation of shock wave at the inlet of test section was observed. Then the conservation equations were mathematically solved with suitable boundary conditions to obtain the analytical solution so as to compare with the experimental results.
