Time-dependent Solidification in a Square Cavity with a Temperature-modulated Liquid Layer Cooled from Above
In this work, we investigate the dynamic response of a solid phase formed during unidirectional solidification below a cooling top wall of a square cavity filled with distilled water and subjected to timevarying heating temperatures at its bottom wall. Assuming a quasisteady state condition, we have formulated a one-dimensional model that predicts the average thickness of the forming solid phas...
متن کاملParticle capture in binary solidification
We examine the interaction of a spherical foreign particle with a propagating solidification front in a binary alloy. Depending on the material properties and the speed of the front, the particle may be pushed ahead of the front, or engulfed and incorporated into the solid phase. We apply numerical boundary integral and continuation methods to determine the critical speed for particle capture, ...
متن کاملSteady-state solidification of aqueous ammonium chloride
We report on a series of experiments in which a Hele-Shaw cell containing aqueous solutions of NH4Cl was translated at prescribed rates through a steady temperature gradient. The salt formed the primary solid phase of a mushy layer as the solution solidified, with the salt-depleted residual fluid driving buoyancy-driven convection and the development of chimneys in the mushy layer. Depending on...
متن کاملArtificial Bee Colony Algorithm in the Solution of Selected Inverse Problem of the Binary Alloy Solidification
The paper presents a procedure for reconstructing, on the basis of known measurements of temperature, the heat transfer coefficient and the distribution of temperature in given region of solidifying binary alloy in the casting mould. Solution of the considered inverse problem is found by applying the finite element method for solving the corresponding direct problem and the Artificial Bee Colon...
