Scaling behavior of coarsening Faraday heaps

Abstract: When a layer of sand is vertically shaken, the surface spontaneously breaks up in a landscape of small conical "Faraday heaps," which merge into larger ones on an ever increasing time scale. We propose a model for the heap dynamics and show analytically that the mean lifetime of the transient state with N heaps scales as N(-2). When there is an abundance of sand, such that the vibrating plate always remains completely covered, this means that the average diameter of the heaps grows as t(1/2). Otherwise, when t… Show more

“…Around 1850 the chemist Justus von Liebig developed a manufacturing process for beef extracts, and founded a company, Liebig Extract of Meat Company . Later Nicholas Kurti, a physicist at Oxford University in 1969 presented a lecture The Physicist in the Kitchen important as a turning point in the relationship between since and cooking [36], [37]. Hervé This in 1980 together with Kurti created the molecular gastronomy, defined as ''a branch of science that studies the physico-chemical transformations of edible materials during cooking and the sensory phenomena associated with their consumption'' [38], [39].…”

“…In 1984 Harold McGee released the book On Food and Cooking: the science and Lore the Kichen. Then in 1988 Hervé This wrote the Casseroles et Éprouvettes [33], [36], [40]. At the beginning of the 21st century there were some collaborations between chefs and scientists: Piere Gagnaire and Hervé This, Heston Blumenthal with Peter Barham and Andy Taylor, Andoni Luis Anduriz and Dani Garcia with Raimundo Garcia del Moral, Ferran Adrià with Pere Castells, and Davide Cassi and Ettore Bocchia [33].…”

“…Other examples of how air affects the dynamics of a dense granular system include the production of so-called Faraday heaps on a vertically vibrated layer of millimeter-sized grains (Pak et al 1995;van Gerner et al 2007van Gerner et al , 2009Pastenes et al 2014;van Gerner et al 2015), the role of air in the Brazil nut effect (M öbius et al 2001, 2005), and the reversal of the Chladni patterns observed on a vibrating plate (van Gerner et al 2011). (a) The blown air effect explains why it is relatively easy to push a reversed glass into a granular bed (Clément et al 2011).…”
