Wed November 30th 2016 16:00 – 16:30 ZH286 | Seminar | Double Diffusive Convection Yantao Yang |
Details:Double diffusive convection (DDC) is the convection flow driven by two scalar components that have very different molecular diffusivities. The most relevant environment is the oceans, where seawater density mainly depends on both temperature and salinity. A fascinating phenomenon induced by DDC in the subtropic ocean is the salt-finger structures and the thermohaline staircase associated to them. In this seminar I will show that, by using large-scale numerical simulations, the transport properties of the salt finger layers, the conditions when the salt finger structures happen, and finally the realisation of the thermohaline staircase state. |
