Undular bore theory for the modified Korteweg–de Vries–Burgers equation
Author(s): L. F. Calazans de Brito and A. M. Kamchatnov
We consider nonlinear wave structures described by the modified Korteweg–de Vries equation, taking into account a small Burgers viscosity for the case of steplike initial conditions. The Whitham modulation equations are derived, which include the small viscosity as a perturbation. It is shown that f…

Universal scaling law for electrified sessile droplets on a lyophilic surface
Author(s): Dipin S. Pillai and Kirti Chandra Sahu
Electrified sessile droplets on solid surfaces are ubiquitous in nature as well as in several practical applications. Although the influence of electric field on pinned sessile droplets and soap bubbles has been investigated experimentally, the theoretical understanding of the stability limit of gen…

Off-lattice Boltzmann simulation of conjugate heat transfer for natural convection in two-dimensional cavities
Author(s): Kuldeep Tolia, Sai Ravi Gupta Polasanapalli, and Kameswararao Anupindi
This study addresses the inadequacy of isothermal wall conditions in predicting accurate flow features and thermal effects in multicomponent systems. A finite-difference characteristic-based off-lattice Boltzmann method (OLBM) with a source term-based conjugate heat transfer (CHT) model is utilized …
