Abstract

. Due to the importance of studying the dynamics of fluids and the impasses in carrying out experiments in this context, it is relevant to develop computational means to visualize flows that are efficient and can offer results that are sufficiently close to reality. That said, this work consists of verifying the IMERSPEC 2D methodology, which combines Fourier pseudospectral and immersed boundary methods to simulate the boundary conditions, based on the simulation of a laminar and two-dimensional flow between two plates over a square cross section ledge. The objective is to validate the methodology and the independence of the results by refining the division number of the physical domain. The results presented in the present work show the velocity fields obtained from four simulations with different placement points and the experimental results by Onur and Baydar (1992), that was used as a reference, are compared. It was possible to observe that the proposal offers a satisfactory approximation to reality under the suggested conditions.

管道内方形弹跳流的计算机模拟

．由于研究流体动力学和在这种情况下进行实验的僵局的重要性，开发有效的计算手段来可视化流动并能够提供足够接近现实的结果是相关的。也就是说，这项工作包括验证IMERSPEC 2D方法，该方法结合了傅里叶伪谱和浸入边界方法来模拟边界条件，该方法基于在方形横截面上的两个板之间的层流和二维流动的模拟。目的是通过细化物理域的除数来验证方法和结果的独立性。本文将4种不同放置点的模拟速度场与Onur和Baydar(1992)的实验结果进行了比较。可以看到，在所建议的条件下，这项建议令人满意地近似于现实情况。
