Nonlinear response of wrinkled premixed flames to time- and space-dependent forcing and stretch
Guy Joulin, Bruno Denet
Premixed-flame wrinkling is studied via a Michelson-Sivashinsky (MS) type of evolution equation retaining the Darrieus-Landau (DL) instability, a curvature effect and a geometric n…
Implosion-explosion in supernovae
Pierre-Henri Chavanis, Bruno Denet, Martine Le Berre +1
Supernovae explosions of massive stars are nowadays believed to result from a two-step process, with an initial gravitational core collapse followed by an expansion of matter after…
Supernova implosion-explosion in the light of catastrophe theory
Pierre-Henri Chavanis, Bruno Denet, Martine Le Berre +1
The present understanding of supernova explosion of massive stars as a two-step process, with an initial gravitational collapse toward the center of the star followed by an expansi…
Premixed flame shapes and polynomials
Bruno Denet, Guy Joulin
The nonlinear nonlocal Michelson-Sivashinsky equation for isolated crests of unstable flames is studied, using pole-decompositions as starting point. Polynomials encoding the numer…
Shapes and speeds of forced premixed flames
Guy Joulin, Bruno Denet
Steady premixed flames subjected to space-periodic steady forcing are studied via inhomogeneous Michelson-Sivashinsky (MS) and then Burgers equations. For both, the flame slope is…
Supernovae: an example of complexity in the physics of compressible fluids
Yves Pomeau, Martine Le Berre, Pierre-Henri Chavanis +1
The supernovae are typical complex phenomena in fluid mechanics with very different time scales. We describe them in the light of catastrophe theory, assuming that successive equil…
