Role of modified cloud microphysics parameterization in coupled climate model for studying ISM rainfall: small-scale cloud model and climate model work better together
Moumita Bhowmik, Anupam Hazra, Ankur Srivastava +4
An unresolved problem of present generation coupled climate models is the realistic distribution of rainfall over Indian monsoon region, which is also related to the persistent dry…
Eulerian-Lagrangian particle-based model for diffusional growth for the better parameterization of ISM clouds: A road map for improving climate model through small-scale model using observations
Moumita Bhowmik, Anupam Hazra, Suryachandra A. Rao +1
The quantitative prediction of the intensity of rainfall events (light or heavy) has remained a challenge in Numerical Weather Prediction (NWP) models. For the first time the mean…
Three-dimensional sedimentation patterns of two interacting disks in a viscous fluid
Yi Liu, Yu Guo, Bo Yang +4
The sedimentation of two spherical solid objects in a viscous fluid has been extensively investigated and well understood. However, a pair of flat disks (in three dimensions) settl…
Simulation of two-phase flows at large density ratios and high Reynolds numbers using a discrete unified gas kinetic scheme
Jun Lai, Zuoli Xiao, Lian-Ping Wang
In order to treat immiscible two-phase flows at large density ratios and high Reynolds numbers, a three-dimensional code based on the discrete unified gas kinetic scheme (DUGKS) is…
Central-moment discrete unified gas-kinetic scheme for incompressible two-phase flows with large density ratio
Chunhua Zhang, Lian-Ping Wang, Hong Liang +1
In this paper, we proposed a central moment discrete unified gas-kinetic scheme (DUGKS) for multiphase flows with large density ratio and high Reynolds number. Two sets of kinetic…
Study of a droplet breakup process in decaying homogeneous isotropic turbulence based on the phase-field DUGKS approach
Jun Lai, Tao Chen, Shengqi Zhang +3
The breakup of a spherical droplet in a decaying homogeneous isotropic turbulence is studied by solving the Cahn-Hilliard-Navier-Stokes equations, using the discrete unified gas ki…
Discrete unified gas kinetic scheme for the conservative Allen-Cahn equation
Chunhua Zhang, Hong Liang, Zhaoli Guo +1
In this paper, the discrete unified gas kinetic scheme (DUGKS) with an improved microflux across the cell interface for the conservative Allen-Cahn equation (CACE) is proposed. In…
Isotropy and spurious currents in pseudo-potential multiphase lattice Boltzmann models
Cheng Peng, Luis F. Ayala, Orlando M. Ayala +1
The spurious currents observed in multiphase flow simulations with pseudo-potential lattice Boltzmann (LB) models are usually understood to be the result of the lack of isotropy of…
A comparative study of immersed boundary method and interpolated bounce-back scheme for no-slip boundary treatment in the lattice Boltzmann method: Part I, laminar flows
Cheng Peng, Orlando M. Ayala, Lian-Ping Wang
The interpolated bounce-back scheme and the immersed boundary method are the two most popular algorithms in treating a no-slip boundary on curved surfaces in the lattice Boltzmann…
A combined immersed boundary and discrete unified gas kinetic scheme for particle-fluid flows
Shi Tao, Haolong Zhang, Zhaoli Guo +1
A discrete unified gas kinetic scheme (DUGKS) coupled with the immersed boundary (IB) method is developed to perform interface-resolved simulation of particle-laden flows. The pres…
Volume-averaged macroscopic equation for fluid flow in moving porous media
Liang Wang, Lian-Ping Wang, Zhaoli Guo +1
Darcy's law and the Brinkman equation are two main models used for creeping fluid flows inside moving permeable particles. For these two models, the time derivative and the nonline…
