Salt Diapirism

Salt Diapirism

A diapir is region of lower density material (in this case salt) intruding into the overlying material. Salt Diapirs are formed through the slow process of evaporation, sedimentation, and compaction. A region experiences frequent flooding Subsequent evaporation will deposit salt The area is covered by later deposition where the overlying material will compact the deeper material. The density of the deeper sediment will increase while the density of salt is less affected by the pressure because of its crystal structure…

Prandtl Number

Prandtl Number

The Prandtl Number is an intrinsic property of a fluid that describes which mechanism dominates heat transfer. Specifically, it is the ratio of momentum diffusivity (how quickly energy is dispersed by convection) to thermal diffusivity (how quickly energy is dispersed as heat). In the abstract, the Prandtl Number describes how quickly a “velocity wave” moves relative to the speed of the “thermal wave” in the fluid. Here, Pr is the Prandtl Number, is the specific heat, is the dynamic viscosity,…
