The following tutorials show how to solve selected fluid flow problems using ANSYS Fluent. The tutorial topics are drawn from Cornell University courses, the Prantil et al textbook, student/research projects etc. If a tutorial is from a course, the relevant course number is indicated below. All tutorials have a common structure and use the same high-level steps starting with Pre-Analysis and ending with Verification and Validation. Pre-Analysis includes hand calculations to predict expected results while Verification and Validation can be thought of as a formal process for checking computer results. Both these steps are extremely important in practice though often overlooked. The pedagogical philosophy behind these modules is discussed in this article from the ANSYS Advantage magazine.
Since the early 2000s, with an increasing number of large-scale plants put into operation (Xiao et al. 2019), researchers have identified the necessity to study the hydrodynamics in full-scale MBRs as the performance of one scale level could not be directly extrapolated to another (Yang et al. 2006). Currently, the design rules of full-scale MBRs are still empirical where it is assumed the system experiences ideal plug flow (Liu et al. 2018). In the wastewater treatment industry, however, it has been reported that the units in a multi-cassette MBR train experience non-plug flow conditions with flows that are not evenly distributed through the system. The unevenly distributed hydraulics is significantly adverse to the MBR application as it results in the insufficient mixing leading to non-uniform nutrient conversion and damage to the membranes (Wang et al. 2010). Experimentally monitoring the full hydrodynamics is complex and challenging due to the turbulent gas-liquid flows interacting with a wide range of membrane configuration characteristics (Martinelli et al. 2010; Sørensen & Bentzen 2018). Thus, research has been carried out using computational fluid dynamics (CFD) to provide predictions of flow characteristics based on conservation laws (mass, momentum, and energy) and semi-empirical formulas in a discretized manner (Hu 2012; Sengur et al. 2015).
