Crosstalk 6. Electronic Warfare during World War IISpeaker. Dr. Swaroop SahooTitle. Electronic Warfare during World War IIAbstract. During World War II various countries attained varied level of technological expertise. The technological expertise or readiness covered various fields of science and technology. Some of the fields with lot of research activities, inventions, design and experiments were electronic warfare and navigational technology.This talk will give an introduction to various electronic warfare techniques, related hardware inventions and uses. It will also provide an insight into the war doctrines of countries and resultant uses of electronic warfare of 1935-45. This talk will also introduce the basic details of the navigational technology used by guided bombers (for bombing and landing) and first missiles (V1 and V2) of World War 2 years.
Talk on active control of compressible flow by Dr. Mahesh Natarajan
Topic: Actuator Selection and Placement for Linear Feedback Control of Compressible Flows
Actuator selection and placement for active flow control is largely based on experience and trial-and-error because of the system’s large dimensionality and complexity. We develop a novel method for estimating how to select and place a linear feedback control system suitable for affecting the dynamics of compressible, viscous flows, that utilizes the information contained within the global stability analysis of the baseflow (a time-averaged solution of the compressible Navier-Stokes equations), obtained from direct numerical/large eddy simulations. A wavemaker, defined by a suitable inner product of the forward and adjoint global modes of the baseflow, identifies regions of the flow-field with high dynamical sensitivity, and an optimization procedure determines effective actuator locations. The algorithm is flexible, and different types of control and feedback can be developed to obtain flow control. The efficacy of the method is demonstrated with two different flow control problems - flow stabilization in a Mach 0.65 diffuser, and the control of noise radiated by a turbulent Mach 0.9 jet.
