Abstract

Venting and Air-Conditioning systems “HVAC”. One of the many suggested solutions for this problem is using flow baffles. In this study, the effect of flow baffles on the mixing of two air streams with temperature difference of 40°F has been investigated. A baffle with different shapes, angles and sizes is installed for each test. An array of thermocouples is employed and connected to data acquisition system to collect the flow temperature distribution at six different stations inside the mixing chamber. Using Tecplot 360, graphs of the temperature distributions inside the mixing chamber are produced. Mixing effectiveness of each test is calculated and minimum and maximum temperatures are also found. Results show that mixing effectiveness is at best when 20”x10” baffle with holes is installed at 20°. As expected, the results also show that the mixing effectiveness of the two flow streams is increased as the downstream distance increased.

Biography

Anan is a graduating senior in the Department of Mechanical & Aerospace Engineering at Missouri S&T. He Graduated from St. Louis Community College and transferred to MS&T in 2010. Anan served as an educational assistant for six semesters at St. Louis Community College, helping with mathematics, physics and basic engineering courses. He participated in multiple research projects involving Orbital Decay, Mathematics, Aerodynamics and thermodynamics. Currently he is employed by the Undergraduate Advising Office as a student mentor & also employed by the Department of Mechanical & Aerospace Engineering as a research Assistant. Anan volunteers as a recruiter for multiple community service projects including Habitat for Humanity and the Catholic Charities of New Orleans. Anan currently is an officer at the Advanced Aero Vehicle Group and a president and a member of many organizations at Missouri S&T. Anan received multiple awards during his years at Missouri S&T including the first place for the engineering category during the 7th Annual Undergraduate Research Conference at Missouri S&T.
