Din Ben Adva | The talk presents two recent studies examining the emergence of corner-flow circulation in confined geometries at highly rarefied conditions, where the characteristic length scale is comparable to the molecular mean free path of the gas.
Prof. Eli Livne | The idea that active control could be used to shape the aeroelastic behavior of deformable aircraft was known to aeroelasticians many years ago. In the late 1960s / early 1970s, with the appearance of “fast enough” actuators and other improvements in control technology’s theory and hardware, active aeroelastic control became feasible.
Ohad Haftka | This talk presents a study of the transmission of sound waves through periodically slitted walls in regimes where the characteristic aperture size and acoustic wavelength are comparable to the molecular mean free path of the gas. The acoustic field is generated by small-amplitude normal oscillations of a vibrating wall located upstream of the perforated plate.
Aharon Renick | Early detection of simulation inaccuracies is critical in system development for increasing result certainty, focusing physical experimentation, and avoiding incorrect conclusions about system performance. This research develops a quantitative methodology to detect "unknown uncertainties“ or “unknown unknowns” within system simulations, in the presence of "known uncertainties“ or “known unknown”.
Saar Levi | Hypergolic propellants are defined by their ability to ignite immediately upon contact, resulting in rapid exothermic reactions occurring without the need for an external ignition source. In hybrid rocket engines, this spontaneous reaction simplifies thruster management, reduces system mass, and enables engine re-ignition.
Avia Rosenfeld | Nanostructured thermites offer unique opportunities for controlling ignition and energy release through engineered material architectures. This seminar presents the fabrication and characterization of Al/SiO₂ multilayer nanothermites produced by physical vapor deposition and examines their thermal and laser-induced ignition behavior.
