Phase-field-lattice Boltzmann study for lamellar eutectic growth in a natural convection melt [PDF]
China Foundry, 2017 In the present study, the influence of natural convection on the lamellar eutectic growth is determined by a phase-field-lattice Boltzmann study for Al-Cu eutectic alloy.

Convective heat transfer in the Burgers-Rayleigh-Bénard system [PDF]
Phys. Rev. Fluids 8,063502(2023), 2023 The dynamics of heat transfer in a model system of Rayleigh-B\'enard (RB) convection reduced to its essential, here dubbed Burgers-Rayleigh-B\'enard (BRB), is studied. The system is spatially one-dimensional, the flow field is compressible and its evolution is described by the Burgers equation forced by an active temperature field.

Analysis of instability patterns in non-Boussinesq mixed convection using a direct numerical evaluation of disturbance integrals [PDF]
, 2009 The Fourier integrals representing linearised disturbances arising from an initially localised source are evaluated numerically for natural and mixed convection flows between two differentially heated plates. The corresponding spatio-temporal instability

Foundations of Convection with Density Stratification [PDF]
, 2022 The phenomenon of thermal and compositional (chemical) convection is very common in nature and therefore of great importance from the point of view of understanding of many fundamental aspects of the environment and universe. A number of books have been written on the topic, such as e.g.

Shape evolution of electrodeposited bumps into deep cavities [PDF]
, 2001 Metal posts and finer pitch solder bumps are the indispensable microconnectors for chip size packaging and are formed by electrodeposition into deep cavities. It is difficult to stir inside these deep cavities.

Magneto-thermal-fluid analysis taking account of natural convection using semi-Lagrange coordinate system [PDF]
, 1999 A method for magneto-thermal-fluid analysis, taking account of natural convection using a semi-Lagrange coordinate system, is developed. The developed method is applied to a simple induction heating model in which the steel plate is heated due to an eddy
