Abstract

A Multi-Faceted Laboratory Module in Cardiovascular Fluid Mechanics to Develop Analysis and Evaluation Skills in Biomedical Engineering Undergraduates (Works in Progress)Beyond the capstone design experience, engineering curricula often struggle to find opportunitiesto systematically instruct students how to evaluate alternative solutions to complex engineeringproblems. Here, a multi-faceted module was designed for an interdisciplinary junior-levelbiomedical engineering laboratory course that guides students through the solution of acardiovascular fluid mechanics problem using three very different approaches in consecutivesessions: an analytical solution, a solution using computational fluid dynamics (CFD), and anexperimental solution.The specific problem involves the determination of the fluid mechanical effect of the presence ofa catheter on aortic blood flow. The analytical approach requires that students solve for thepressure drop per length based on solutions derived from reduction of the Navier-Stokesequations. Students are then introduced to CFD for the first time in the curriculum to solve theproblem. Challenges such as mesh-independence are explored in the context of this problem, asare potential benefits, such as versatility in the geometric placement of the catheter and extensionto non-Newtonian blood models. Finally, in the experimental session, students gain experienceusing peristaltic pumps, pressure and flow sensors, and various types of tubing and fittings asthey design and implement an experiment to determine the pressure drop per length across anaortic tube model containing a catheter, while accounting for confounding minor losses.As each approach introduces a unique set of limitations based on implicit assumptions ormethodologies used, students are asked to consider the validity and benefits of each approachfollowing its implementation. Upon completion of the three-week module, they are asked togenerate pairwise comparisons between the approaches and then to evaluate all three alternativesolutions and make a defendable recommendation on which approach is best for a prescribedscenario. Assessment tools are currently being devised to determine the extent to which analysisand evaluation skills are developed by students as a result of completing this module.
