Gupta University of Toledo RSVP and Information: https://conta.cc/3d1oAdU Event Calendar Upcoming events: aiaa-lalv.org/events 10:05 AM Dr. Chandrashekhar Sonwane (Welcome Message) 10:10 AM Dr. Brian Brady (Welcome Message) 10:15 AM Mr. Casey Moninghoff (AIAA LA LV Section STEM K-12 Activities) 10:20 AM Dr. Claire Leon (40 Years of Overcoming Challenges) 11:20 AM Dr. Anju Gupta (An insight on Graphene Based Multiscale Coatings for Phase Change Heat Transfer Applications) 12:30 PM Adjourn40 Years of Overcoming Challenges Claire Leon will discuss her experiences working in industry, for the government and academia, and offer suggestions for working professionals in various phases of their careers Dr. Claire Leon started her career at Hughes, Space and Communications Group in 1979. She gained experience across the company, through positions of increasing responsibility in Systems Engineering and Program Management. She was promoted to Vice President of Navigation and Communications Systems within Boeing, in 2008, responsible for the AF satellite programs, as well as a number of classified programs. She transitioned to VP of National programs later in 2008, where she led the program turn around for a critical ACAT I program on the customer Contractor Responsibility Watch List (CRWL) that became a high performing program, delivered outstanding operational capability. She also transitioned the National Space and Communications Programs (NSCP) from a cost-plus to fixed price in response to customer affordability concerns. She retired from Boeing, in 2013, as the Vice President of National Programs. Dr. Leon became a member of the Senior Executive Service in the Air Force, as the Director of the Launch Enterprise Directorate, at the LA Air Force Base, California, in 2014. She was responsible buying and launching rockets for the DoD, as well as leading the transition to the next generation of launch systems. She is currently running the Graduate Program in Systems Engineering at Loyola Marymount University, as well as consulting for SAIC and Inside Out Learning. Her education background includes: Ph.D. Executive Management, Drucker School of Business, CGU, Claremont, Ca, 2010, Masters of Business Administration, UCLA, Los Angeles, Ca, 1995, Masters of Management, University of Redlands, Redlands, Ca, 1986, BS, Mechanical Engineering, George Washington University, Washington D.C., 1979 Description of Dr. Claire Leon's Consulting Services Perform management consulting for Inside Out Learning, and SAIC, and possibly additional technical management companies. Tasks include executive presentation support, coaching, strategic planning, feedback on management approach for resolving challenging problems, as well as support to independent program review teams. An insight on Graphene Based Multiscale Coatings for Phase Change Heat Transfer Applications (Dr. Anju Gupta will also talk about her passion for STEM, what made her study STEM studies dueing college. What message she has for all the girls and boys out there and the parents.) Phase change heat transfer is crucial to various engineering applications. Some prominent examples include distillation reboiler, nuclear reactor, high-powered electronic systems, and refrigeration. Boiling is a heat transfer process accompanied by phase change from liquid to vapor, subsequently, pool boiling involves the boiling of a stagnant liquid over a heated surface. This talk aims to examine the physical mechanisms of boiling heat transfer that are of prime importance to quantify the efficacy of the process. For various manifestations, the pool boiling performance of a surface is dictated by higher critical heat fluxes and heat transfer coefficients. This talk examines various strategies to create multiscale surface-active engineered surfaces with tunable properties essentially roughness, porosity, hydrophilicity, wickability and wicking rates and their influence on the heat transfer properties. First, several surface engineering methods and the resultant physical properties that can effectively modify the vapor bubble dynamics will be discussed using multiscale graphene coatings as an example. The second part of the talk will focus on electrodeposited graphene nanoplatelet (GNP) enriched copper composite coatings formed systematically by increasing the GNP concentration to yield hierarchal porous structures. These superhydrophilic with very high wicking rates resulted in high critical heat flux (CHF) and heat transfer coefficient (HTC). The copper/2 wt% GNP (weight/volume) composites exceeded the highest pool boiling performance reported in literature with a CHF of 286 W/cm² and HTC of 204 kW/m²-°C, representing an improvement of 130% in CHF and 290% in HTC over a polished copper surface. High thermal conductivity along with improved hydrophilicity and wickability of the copper/GNP coatings are attributed for the enhanced CHF. High-speed images revealed reduced bubble departure diameters and micro-size pores on the electrodeposited surface serving as nucleation sites. The increase in the bubble frequency and delayed formation of vapor blanket resulted in enhanced heat transfer properties. Dr. Anju R. Gupta: Anju Gupta is an Assistant Professor in the Department of Mechanical, Industrial and Manufacturing Engineering at the University of Toledo. She received her PhD in Chemical Engineering from University of Rhode Island. Her Interfacial Thermal and Transport lab studies phase change heat transfer on novel substrates, and transport mechanisms across the cell membrane. Dr Gupta has received funding from NSF, ACS PRF and holds two provisional patents. Dr. Gupta is an active member of AIChE , ACS, North American Thermal Analysis Society and ASEE and has published her work in a variety of scientific and education journals.
