Further information can be found below. [cid:image001.jpg@01DA8118.6C280050]<https://maillinks.purdue.edu/t/45922180/1710281286/79579849/0/1006672/?x=27…> Dr. Hansol Wee Post-Doctoral Research Associate Davidson School of Chemical Engineering Purdue University Bio: After receiving his Bachelors of Science degree in Chemical Engineering from Sogang University in 2014, Dr. Hansol Wee continued on in the same department to receive his Master of Science degree in Chemical Engineering under the guidance of Professor Won Bo Lee (now at Seoul National University). He then obtained his PHD under the guidance of Professor Osman Basaran at Purdue University in 2023. "Effects Of Surface Viscosity On Breakup Of Liquid Threads" April 4, 2024 Seminar: 3:00 p.m. - 4:15 p.m. ET FRNY G140 - Reception at 2:30 p.m. in FRNY Atrium - Abstract: Free surface flows exhibiting hydrodynamic singularities are ubiquitous in technology, daily life, and nature. Examples of such flows include dripping faucets, inkjet printing in both industrial and personal settings, drop-by-drop manufacturing, microarraying, crop spraying, atomization or spray coating, fuel injectors, as well as natural occurrences like fountains and waterfalls. Additionally, they are encountered during the usage of numerous consumer and household products like paints, cleaners, cosmetics, drugs, and foods. After giving a quick overview of the current understanding of pinch-off singularities which arise during the breakup of liquid drops, jets, and threads, the majority of the presentation will be devoted to the role of surface-active additives on pinch-off. Surfactants residing at fluid interfaces not only reduce and induce gradients in surface tension but can also induce additional surface rheological or viscous effects in response to dilatational and shear deformations. Both surface tension and surface viscosities are dependent on surfactant concentration. While the measurement of surface tension and its effects on interfacial flows have become standard practices, determining surface viscosities remains notably challenging. This challenge persists because existing measurement methods often fail to isolate the effects of surface viscous stresses from those attributed to Marangoni stresses. Consequently, the quantitative characterization of surface viscous effects in interfacial flows remains arduous. To address this difficulty, a combined asymptotic and numerical analysis is presented for the pinch-off of a surfactant-covered Newtonian liquid jet. Asymptotically exact solutions derived from slender-jet theory and numerical solutions of the full three-dimensional but axisymmetric (3DA) equations are provided for jets with and without surface rheological effects. The analysis reveals that Marangoni stresses become negligible near pinch-off compared to other forces. Furthermore, it demonstrates that the rate of jet thinning is significantly reduced by surface viscous effects. Simple analytical formulas for inferring surface viscosities are derived from the dynamics near the pinch-off singularity, offering straightforward means for measuring surface viscosity. 3DA simulations confirm the validity of the asymptotic analyses.

Hot water addition side
by Valley, Jeffrey L 27 Mar '24

27 Mar '24

BE ADVISED - This morning plumbers shut down the hot water on the addition side of the building to flush the system out and to make repairs. When turning the water pressure back on, the usual result is breaking off of sediment in the pipes. Opening the faucets and letting them run for a while will flush all of it out of the pipes. Thanks.

AICHE 2024 ChE Crewneck Sale Ends 3/24!
by Raderstorf, Karissa L 18 Mar '24

18 Mar '24

Just a friendly reminder that it's time for Purdue AIChE's annual crewneck sale! The 2024 Purdue ChE Crewnecks will be sold at $15 each. Link to the 2024 ChE Crewneck Order Form: http://tinyurl.com/2024ChECrewneck<https://nam04.safelinks.protection.outlook.com/?url=http%3A%2F%2Ftinyurl.co…> IMPORTANT PAYMENT INFO: * If you are paying with a credit/debit card, please make your payment on TooCOOL before Sunday, 3/24. If payment is not received by Sunday, 3/24, we reserve the right to sell your crewneck, even if you have completed this form. Please ensure payment is made before Sunday, 3/24, to secure your purchase. * If you are paying with cash, you can present the cash when you pick your crewneck up. * You can also purchase the crewneck after it arrives (either by cash or by TooCOOL), but your size is NOT guaranteed. Filling out this form and paying by TooCOOL before Sunday, 3/24, will guarantee one for you. TooCOOL Link: https://tinyurl.com/TooCOOL24ChECrewneckUpdated<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftinyurl.c…> Alternatively, 1. Google "Purdue TooCool" 1. Open Website 1. Find "American Institute of Chemical Engineers" 1. Select "ChemE Crewnecks 2024" with the $15 clothing option. We estimate the crewnecks to be ready for pick up in mid-April to end-April. There will be many time frames during the last weeks of April to pick up your crewneck. Additionally, you are only eligible for a size swap once everyone has picked up their crewneck, and we can exchange your crewneck with one of our extra sizes. If you are not currently on campus, AIChE will NOT be holding your crewneck. If needed, please arrange for someone to pick up and hold onto your crewneck for you. If you have any questions, please reach out to Katie Huang (huan1666(a)purdue.edu<mailto:huan1666@purdue.edu>). Have a great day!

Good morning, everyone, On behalf of the ChE sustainability committee, please see below (and attached) an invitation to attend the "Sustainability initiatives in industry" session scheduled for this Wednesday, March 20, from 3:30-4:20 pm in BHEE 170. The session will focus on advances in plastic recycling and you will have the chance to learn from experts in the filed representing Procter and Gamble Co. (P&G), who will talk about the ground-braking PureCycle patented process for recycling polypropylene plastic waste to transform it into ultra-pure recycled resin. Space is limited and registration is required. Please register at this link: https://tinyurl.com/56d9hu8d<https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftinyurl.c…> by 12 noon on Wednesday, March 20 if you plan on attending. Thank you, Gabriela [cid:image001.jpg@01DA7922.C5C4A9E0] __________________ Gabriela Nagy, PhD Industrial Education Director Davidson School of Chemical Engineering Room FRNY G051 Purdue University Tel: (765)-496-1710 E-mail: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>
