Havelock's theory for acoustic-gravity waves in deep water
 

Raphael Stuhlmeier

PhD in Mathematics at the University of Vienna

In this talk, we will investigate the linearized theorey of waves generated by a wave-maker in compressible flow. In addition to the propagating and evanescent waves found in the incompressible case, new modes then appear which incorporate both the effects of gravity and compressibility - called acoustic-gravity waves. The treatment of this problem in infinite depth is an exercise in classical analysis, and leads to a version of Havelock's wave-maker theorem for compressible flows. We shall discuss the asymptotic behavior of these new waves, give some simple examples for line wave-makers, and look briefly at some related problems and open questions.

Short Bio:
 

Raphael Stuhlmeier completed a PhD in Mathematics at the University of Vienna, Austria in 2014, treating primarily nonlinear water waves with vorticity, including extensions of Gerstner waves and solitary waves on shear flows. Since then, he has been a Postdoctoral Fellow at the Faculty of Civil & Environmental Engineering, Technion - Israel Institute of Technology, working primarily on the theoretical basis for wave-power harvesting in the open seas, and occasionally on other topics in water waves.
