• Séminaire PMMH – Christophe Gissinger (LPENS)
  Vendredi 13 mars de 11h00 à 12h00 - Salle réunion PMMH 1
  Thermoelectricity at liquid interfaces
  Thermoelectricity refers to the direct conversion of a temperature difference into an electric current (Seebeck effect), and vice versa. In conventional solid-state devices, this mechanism is generally limited by the essentially linear relationship between the generated current and the applied temperature (…)
• Séminaire PMMH – Cédric Beaume (U. Leeds)
  Vendredi 20 mars de 11h00 à 12h00 - Salle réunion PMMH 1
  A fluid instability at the origin of salt polygons
  Dry salt lakes form spectacular landscapes in arid regions. Strong evaporation and weak precipitation (but also human intervention) can progressively deplete lakes of water, leaving surfaces that appear dry while the water table remains shallow. In such environments, evaporation continues to play an important role, (…)
• Séminaire PMMH – Philippe Beltrame (U. Avignon)
  Vendredi 27 mars de 11h00 à 12h00 - Salle réunion PMMH 1
  Ratchet Effect for Selective Transport of Microparticles in Fluid Suspension
  The ratchet effect enables directed transport of particles in noisy systems, even in the absence of a net force (zero bias). When exploited in periodic structures, this phenomenon paves the way for innovative applications in selective microparticle sorting. This seminar will present a theoretical analysis of (…)
• Séminaire PMMH – Jonas Miguet (MSC, Univ. Paris Cité)
  Vendredi 3 avril de 11h00 à 12h00 - Salle réunion PMMH 1
  Antibubbles : optical interferometry, gas transfers and acoustic signature
  An antibubble is a spherical thin film of gas, that encapsulates a droplet, within a liquid medium. The typical size of an antibubble is one centimeter while the thickness of the gas film is of micrometric order. Because of the higher hydrostatic pressure at the bottom, the gas film undergoes a (…)
• Séminaire PMMH – Gautier Verhille (IRPHÉ)
  Vendredi 10 avril de 11h00 à 12h00 - Salle réunion PMMH 1
  Formation and fragmentation of fiber aggregate in turbulent flows
  Fiber aggregates are commonly encountered in environmental and industrial flows (paper industry, fiber recycling, etc.). However, the physical mechanisms leading to their formation are still misunderstood. Hence, there is still no clear answer to simple questions such as : how long will it take for an aggregate to (…)
