A point-force model is used to study turbulent momentum transfer in the presence of moderate mass loadings of small (relative to Kolmogorov scales), dense (relative to the carrier phase density) particles. Turbulent Couette flow is simulated via direct numerical simulation, while individual particles are tracked as Lagrangian elements interacting with the(More)

Key Points: • Spray dominates enthalpy flux at the hurricane air-sea interface • Enthalpy fluxes can be estimated from dropsonde thermodynamic data • Trends of enthalpy flux coefficient can be misleading due to uncertainty Evidence of spray-mediated air-sea enthalpy flux within tropical cyclones, Abstract It has long been conjectured that spray ejected from(More)

Direct numerical simulations are performed of turbulent planar Couette flow which are seeded with two-way coupled particles at low volume concentration. Based on an understanding of the development of particle stress (horizontal momentum carried vertically on average by the particle phase) in monodisperse systems at various particle Stokes numbers, several(More)
Direct numerical simulations of an Eulerian-based carrier phase are performed which are two-way coupled in momentum and energy to Lagrangian droplets within a Boussinesq-type incompressible formulation, where the droplets are allowed to evaporate and condense and are thus coupled to the vapor field of the carrier phase. Turbulent planar Couette flow is(More)
