A Proposed Particle Image Velocimetry (PIV) System for Instructional Purposes in a Modern Mechanical Engineering Undergraduate Laboratory Program Abstract

Hands-on laboratory skills play a vital role in providing the students with genuine understanding of the scientific fundamentals and their application in solving of the real-life engineering problems. One of the key areas of focus at our institute is state of the art modern laboratories that can prepare the next generation of mechanical engineering students to assume successful career paths in the Energy industry in the 21st century. Among the essential topics in fluid mechanics, the study of fluid flow visualization using non-destructive optical methods is extremely important. Particle image velocimetry (PIV) is a modern and powerful method for investigating fluid flow. PIV has many applications in research and engineering, including in the oil/gas and the broader energy area. The purpose of this paper is to propose a PIV system that can effectively serve to cover the fundamental operation of the device, its applications, and demonstration of fluid mechanics concepts through carefully designed experiments.

I. Introduction

Our institute is supported by a consortium of five major oil companies. The prime sponsor has diverse interests in the oil and gas industry, including various subsidiaries and operating companies in the major business areas of exploration, drilling, production, refining, and gas processing operations, as well as transportation and marketing. Our institute offers undergraduate (and soon graduate studies) in the five major engineering fields of chemical, electrical, mechanical, petroleum, and petroleum geosciences engineering. Additional engineering disciplines are expected to be added in the future, in-line with the needs of the sponsoring consortium and the local oil companies. We also provide research and continuing education services to our sponsors, thus justifying the need for state of the art laboratories at both undergraduate and graduate levels.

Graduates from the Mechanical Engineering Department will work for the sponsoring companies as field test engineers, laboratory test engineers, design engineers, development engineers, project management engineers, and research engineers. We must prepare the students with the ability to undertake a variety of engineering tasks in the oil and gas industry. As a senior level course, the Advanced Measurement Laboratory course is a technical elective in the Mechanical Engineering program. The objective of this course is to familiarize future engineers with modern and advanced measurement techniques, such as the diagnostic laser method, that are widely used in the petroleum and broader energy industry.

Flow measurement using laser diagnostics allows engineers to obtain significant information about the dynamics of the flow in complex geometries. Different types of laser diagnostics, such as laser doppler anemometry (LDA), particle imaging velocimetry (PIV), and planar laser- induced fluorescence (PLIF), are used to determine local velocity, 2D velocity, and concentration measurements, respectively1-5.
