From: Valley, Jeffrey L Sent: Monday, August 03, 2015 8:41 AM To: 'cheq(a)ecn.purdue.edu'; 'chmegrad(a)ecn.purdue.edu' Subject: OSHA Inspections BE ADVISED - Tentatively tomorrow morning , Aug. 4th , OSHA will begin inspections of all the rooms in the building to make sure we are compliant. The Dept.'s Safety Committee conducted an inspection in June and reported back any violations or possible violations that were found and hopefully they have been corrected since then. Please check your office or labs again to verify that all is as it should be according to policy. If you have any questions please contact me. Thanks. Jeff Valley

My term as Head
by Varma, Arvind 01 Aug '15

01 Aug '15

Dear Colleagues, I joined Purdue as ChE Head on January 1, 2004. Following two five-year terms, beginning January 1, 2014 I accepted a partial term of "approximately three years." In my mind, approximately 3 years meant 2.5 to 3.5 years. Over the past several months, I decided to make the term duration definitive. I am writing to inform that I plan to leave my Head position effective July 31, 2016 - 2.5 years into my current term. Dean Leah Jamieson is aware of my plans - the full one-year notice will permit her to conduct a search to appoint a new Head effective August 1, 2016. My personal plan is to be on a one-year leave and return to the faculty effective August 1, 2017 to continue my teaching and research programs. It has been my honor to serve as the 10th Head of our School, since its founding on June 14, 1911. I have tried my best to uphold the high standards of leadership and excellence established by my distinguished predecessors. During my service, I have been overwhelmed by the strong support of the faculty, staff, students, alumni, corporate and other friends. The support of the College administration, notably by Deans Linda Katehi and Leah Jamieson, has also been very important for me and our School. I thank all for the opportunity to serve and look forward to completing the last year of my term to help raise our School to even greater heights - our collective future is brilliant! With best wishes, Arvind Arvind Varma R. Games Slayter Distinguished Professor Jay and Cynthia Ihlenfeld Head of Chemical Engineering Purdue University

Nicole Devlin Dissertation Defense, Monday, August 3rd, at 1:00 p.m. in FRNY 3062B

This e-mail is to announce that Nicole Devlin will be defending her dissertation, The Separation of Two Different Sized Particles Via Droplet Evaporation, on Monday, August 3rd, at 1:00 p.m. in FRNY 3062B. The dissertation is directed by Dr. Harris, and the abstract is below. All are welcome to attend. Abstract: An evaporating droplet with different sized particles was examined both computationally and experimentally. During evaporation, particles can naturally separate into concentric rings by size with one ring per particle size. The objective of this investigation was to determine factors that contribute to this separation process. Computationally, the finite element method was used to solve a transport model for the droplet fluid velocity in two directions (radial and axial), the pressure, the temperature inside the droplet, and the concentration of each particle size. Experimentally, an aqueous droplet with 1 µm and 3 µm polystyrene spheres was evaporated on a silicon substrate. It was determined that several factors contribute to particle separation. First, the surface tension driven Marangoni currents caused by evaporative cooling on the droplet surface significantly affect the separation process. The Marangoni currents keep the particles suspended in the droplet for the majority of the evaporation, which allows for separation by geometric constraints. A maximum packing concentration for the spheres was implemented in the simulations and without Marangoni currents, the maximum packing limit is reached quickly, before separation can occur. Second, gravity was determined to have a large effect on particle deposition. Pendant droplet simulations and experiments result in larger (3 µm) particles depositing in the center of the droplet and the smaller (1 µm) particles depositing on the edge of the droplet. The third investigation was a computational study on the influence of buoyancy-driven flow in an evaporation. It was determined that buoyancy-driven flow is present in the initial stages of droplet evaporation, especially when the environment is humid. And finally, an experimental investigation on the surface roughness and droplet contact line depinning on particle separation was conducted. Both high surface roughness and contact line depinning prevent the separation of particles in an evaporating droplet.
