...V.R. Voller Purpose The purpose of this study is to evaluate the performance of various numerical schemes for solving moving boundary problems that involve chemical reactions. Design/methodology/approach A one-dimensional test problem involving the infiltration of fluid into an initially dry...

... hexagonal cells, the side lengths of the shared walls were adjusted to construct alveolar pores. Periodic moving boundaries with the same phase were set for all walls to describe synchronous contraction and expansion of the bronchi and alveoli. Findings More realistic flow characteristics in the distal...

...: an approximate Riemann solver to construct upwind fluxes, the MUSCL extension to achieve high-order accuracy, a splitting approach to solve source terms, a self-adapting method to expand the computational domain for projectile motion and a control volume conservation method for the moving boundary. Findings...

... with phase change. The solver for the basic equations is the SIMPLE algorithm with a non‐staggered grid arrangement. The space conservation law is invoked and applied for the explicit tracking of a moving boundary with a moving mesh. For mapping complex geometries a multi‐block iteration strategy is employed...

...Yiqiang Zhang; J.I.D. Alexander; J. Ouazzani Free and moving boundary problems require the simultaneous solution of unknown field variables and the boundaries of the domains on which these variables are defined. There are many technologically important processes that lead to moving boundary...
