Flow density model
WebJul 23, 2024 · Next, the density and viscosity of the fluid are specified, and an object of the class Fluid is created. #### FLUID PROPERTIES rho=1 #Density of fluid mu=0.01 #Viscosity of fluid #Create an object of the class Fluid called water water=Fluid(rho,mu) Third, we create Boundary objects to set velocity and pressure boundary conditions. WebDensity currents are caused by density differences due to temperature, total dissolved solids and suspended solids. For example, at 25°C (77 F) it takes approximately 330 mg/1 of dissolved solids or 420 mg/1 of suspended solids (p = 2.65) to equal the density difference caused by I oc temperature change (Ford and Johnson I983).
