ME-EM Graduate Seminar: Development of a Low Dimensional Two-Phase Thermal Model for Subsea Pipelines

apr23The ME-EM Graduate Seminar speaker on Thursday, April 23 at 4:00 in 103 EERC will be Dr. Reza Tafreshi from Texas A&M University at Qatar.

The title of his presentation will be ‘Development of a Low Dimensional Two-Phase Thermal Model for Subsea Pipelines’.

Rising global energy demand has led to new operational challenges in unfamiliar environments, with higher temperature gradients. The challenges directly address safety, environmental and economic issues. Due to the low subsea temperatures and relatively higher petroleum fluid temperature in deep water pipelines, convectional heat losses occur from the petroleum fluids to the surroundings. This heat transfer is necessary to be considered, to ensure the proper flow of petroleum fluids. While conventional equivalent heat transfer models are easier to compute, they are not accurate enough to reflect the changes that would occur within a fluid due to different multiphase flow regimes and proportions. The objective is to develop a low dimensional and low computational equivalent thermal model of subsea fluids, which can predict two-phase fluid temperatures along insulated subsea pipelines. The developed heat transfer model combines the application of two-phase heat transfer coefficient model with fluid properties obtained from a low dimensional fluid model developed by our group. The presented model identifies the effect of heat transfer in subsea pipelines for two-phase fluids for normal operating and shut-down conditions. This model, when compared with industry standard software, showed that results were obtained with similar accuracy with approximately 1000 times less computational time.
Some other current research activities will be also discussed.

Reza Tafreshi received his B.Sc. and M.Sc. degrees from the K.N. Toosi University of Technology, Tehran, Iran, in 1991 and 1995, respectively, and his Ph.D. degree in mechanical engineering from the University of British Columbia (UBC), Vancouver, BC, Canada, in 2005. He was a site engineer and then a project manager at PoloDej Company, Tehran, from 1995 to 1999. From 1999 to 2000, he was a Research Engineer with the Department of Mechanical Engineering, UBC. Dr. Tafreshi was a recipient of the Michael Smith Foundation for Health Research Award, Canada, and was a postdoctoral fellow at the Department of Electrical and Computer Engineering, UBC, from 2005 to 2006. He was a Visiting Assistant Professor with Texas A&M University, College Station, TX, in 2006. In 2007, he joined Texas A&M University at Qatar, Doha, Qatar, where he is currently an Assistant Professor. His research fields include dynamic systems and controls, machine fault diagnosis, condition monitoring, and biomedical engineering.

According to the Order of the Engineer manual: The Order of the Engineer is a solemn obligation to oneself to uphold devotion to the standards and the dignity of the engineering profession. It is an obligation to turn to practical use the principles of science and the means of technology…to serve humanity by making the best use of earth’s precious wealth.

The Obligation is a creed similar to the oath attributed to Hippocrates (460-377 B.C.) that is generally taken by medical graduates and which sets forth an ethical code. The Obligation likewise, contains parts of the Canon of Ethics of major engineering societies. Initiates, as they accept it voluntarily, pledge to uphold the standards and dignity of the engineering profession and to serve humanity by making the best use of Earth’s precious wealth.

ME-EM Students Win Awards at Design Expo 2015

138IMG_9708The mechanical engineering-engineering mechanics department held its semi-annual Senior Capstone Design Day Program on Tuesday April 21, 2015. Eighteen teams presented the fruits of their efforts over the past two semesters during presentations to industry reps, faculty, staff, students and MEEM External Advisory Board members. The teams displayed posters and, in some cases, their prototypes in the rear first-floor hallway of the MEEM building. This year’s project customers include American Axle & Manufacturing, Chrysler, John Deere, MacLean-Fogg, and others. Most presentations are open to the public.

Project Overview: Our team is dedicated to working on bicycle and bicycling industry related projects. For the 2014-2015 academic year, Velovations has more than twenty-five students from various majors divided into four projects. The projects are: a pedal that offers the ability to transition from clipped in to a platform and back at the push of a button; a system to allow tire pressure change on the fly;
an inexpensive winter commuting tire; and an innovative exercise system for wheelchair users that will allow further physical research. Velovations projects cover the complete product development
range, from idea conception, research, and development, to customer communication, testing, and ultimately manufacturing.

Project Overview: Our goal is to design, engineer, build, and test a split decklid adapted from the current Chrysler 300 architecture. This decklid system will provide the customer both the access required of typical decklids without the upswing of the lower waterfall area and the added feature of a tailgate style lower swing out panel which will provide a surface for tailgate functions. This feature is rare in the industry and provides an opportunity for segment differentiation creating a unique selling point.

Sponsor: John Deere

Project Overview: This design team is working with John Deere to develop a new dynamometer torque meter calibration device. A dynamometer, commonly referred to as a dyno, is a popular test instrument used to measure variables such as torque, speed, and power output. The current calibration method used by John Deere utilizes a static weight stack attached to a moment arm. This design must be replaced because it exceeds the dynamometer test cell envelope, is difficult to transport from test cell to test cell, requires considerable time and effort for two workers to assemble and disassemble, and requires the repetitive lifting of 40 to 45 pound weights.
