Mathematical Simulation of Honeycomb Weathering via Moisture Transport and Salt Deposition

چکیده
Honeycomb weathering is a common phenomenon found on various rock surfaces all around the world. However, honeycomb formation mechanisms are still poorly understood. In this study, we propose model describing moisture transport within sandstone and erosion resulting from salt deposition during evaporation of off surface. The based non-linear diffusion equation, where volumetric content combined parameter accounting for gas (vapor) content. accounts several-orders-of-magnitude decrease in diffusivity, observed drying. It was assumed that occurs when front located close to depth proportional flow rate through drying ABAQUS finite-element software suite used numerical solution equation. iterative scheme simulation different cycles implemented using Python programming language. Computations were conducted 2D setting square with dimensions 50 mm × mm. Simulation results demonstrate possibility obtaining landform shapes (honeycombs, tafoni) by varying only value distribution at bottom side, simulating internal wetting rock.

Mathematical model of honeycomb construction
We developed a mathematical model and an algorithm for numerical treatment of a model of honeycomb construction in a beehive. The model contains essential features of the bee-bee and bee-wax interactions, and in a qualitative way captures the dynamics of parallel comb construction. The construction is represented by a set of dynamical coupled partial differential equations for the density of be...
متن کاملMoisture Permeability Data Presented as a Mathematical Function Applicable to Heat and Moisture Transport Models
The physics of moisture transfer is complex and as a result modelling is normally carried out on a macroscopic basis, with empirical coefficients used to simulate the transport process. These coefficients are not single values but depend on the moisture content of the material. The application of this data within the simulation environment requires the determination of a systematic methodology ...

15 صفحه اولVisual Simulation of Wood Weathering
The aging process of material is an unavoidable natural phenomenon. Thus, several CG techniques for representing aging phenomena, such as metal corrosion and stone weathering, have been studied. In this paper, we propose a visual simulation method of wood weathering. First, we present the wood model in consideration of branching. Then, we give the algorithm for representing the weathering of th...
