Addressing Instrumentation Needs for Turbomachinery Applications: Goals, Challenges, and New Solutions
Tuesday, January 22, 2019;
3:35 pm
220 Hammond Building
Speaker: Reid Berdanier from The Pennsylvania State University
Experimental methods for turbomachinery are inherently driven by a desire for higher accuracy measurements, increased resolution, and the ability to adequately validate computational predictions. Unfortunately, as gas turbine applications reach for higher temperatures to boost efficiency, instrumentation goals become increasingly difficult to achieve. As a critical step to achieve these targets, research facilities with scaled conditions are often used as intermediate demonstration sites in the instrumentation development process. The Steady Thermal Aero Research Turbine (START) at Penn State represents a state-of-the-art facility capable of shepherding instrumentation development from the bench to the engine. This talk will introduce challenges facing next-generation turbine instrumentation and propose potential strategies for success.

Leonhard Center Workshop Series: The Ins and Outs of Classroom Flip
Thursday, January 24, 2019;
12:00-1:30 PM
202 Hammond (Stavely Conference Room)
Speaker: Sarah Zappe from The Pennsylvannia State University
This semester, the Leonhard Center will launch a 3-part workshop series entitled, “The Ins and Outs of Classroom Flip.” With classroom flip, the activities that students usually do during class and out-of-class are reversed. Lecture is removed from class time and provided online through videos or other activities. In-class time is reserved for students’ homework or other active instructional techniques. During this workshop series, we will provide an introduction to classroom flip and explore student activity options for both inside and outside the classroom.
While attending all three workshops will provide the most comprehensive understanding of classroom flip, faculty are welcome to attend any or all of the workshops that fit their schedules. The topics and dates of the workshop series are listed below:
Classroom Flip: Getting Started (January 24 from 12-1:30 p.m.) – In this workshop, we will provide a framework for classroom flip along with tips for getting started. Common challenges along with possible solutions will be discussed. This workshop will be led by Sarah Zappe from the Leonhard Center.
Classroom Flip: Outside the Classroom (February 14 from 12-1:30 p.m.) – In this workshop, we will discuss strategies and tools to create instructional material to be used in the out-of-the-classroom time during classroom flip. This workshop will be led by Casey Fenton from the Office for Digital Learning.
Classroom Flip: In-Class Activities (March 19 from 12-1:30 p.m.) – In this workshop, we will wrap up our discussion of classroom flip by exploring various instructional techniques and activities that you can do during class time when implementing classroom flip. This workshop will be led by Stephanie Cutler from the Leonhard Center.

Ultrasound for advanced material characterization

Ultrasound for advanced material characterization
Advances in manufacturing processes and new alloy development have emphasized the need for nondestructive approaches to fully qualify components. Ultrasonic attenuation and scattering methods have been extensively studied in both flaw detection and material characterization. Specifically, elastic wave scattering by grain boundaries in polycrystalline media have been shown to correlate to microstructural properties. Attenuation and diffuse-field scattering studies have shown a clear dependence on both grain morphology (geometry) and material texture (macroscale anisotropy). In this seminar, scattering models are employed to account for complex microstructural features including grain elongation, grain size distributions, and stress. The benefits of these modeling advances are exemplified through experimental testing of various materials, including additively manufactured components. Experiments conducted on titanium specimens depict differences in the response of forged and additively manufactured sections of a component. The effects analyzed herein play an important role in the use of ultrasonic scattering measurements for microstructure and material characterization.

Advancing the science of metallic 3D printing through ultrasonic characterization of laser-generated melt pools
Wednesday, February 6, 2019;
3:35pm - 4:25pm
114 EES Building
Speaker: Christopher Kube from Penn State, Engineering Science and Mechanics
Over the past decade, we have witnessed the emergence of functional additively manufactured (AM) metallic parts integrated into modern technology. This is evidenced in the usage of AM metallic rockets, submarine propellers, nuclear reactor components, munitions, and car components. While advances in this area are being realized, these advances are not addressing the full potential of metal AM. A significant advance will be seen when the AM process produces parts that perform exactly as expected in their intended application, without exception. An increase in fundamental knowledge involving the influence of the AM process on the resultant metallic microstructure along with quality control procedures that have microstructure-property sensitivity are two areas of need that can help fulfill the promise of metallic AM.
In this presentation, a review of present applications involving metallic AM parts is highlighted followed by efforts being undertaken by the Penn State Ultrasonics Laboratory (PennSUL) to address the two areas of need. Specifically, research in the development of ultrasonic technology to monitor in situ laser generated melt pools is provided. Ultrasound is a unique modality that allows us to characterize mechanical properties and microstructure as they are manifest as the melt pool solidifies. Such characterization has potential to (1) enhance our knowledge of the AM process in relation to microstructure formation and (2) provide information on the quality of the formed microstructure and the resultant part.

Diagnostic and Therapeutic Ultrasound: Applications for Earth and Space Exploration
Wednesday, February 13, 2019;
3:35pm - 4:25pm
114 EES Building
Speaker: Julianna Simon from Penn State, Acoustics
Spaceflight presents many biological and technological challenges that are similar to those found on Earth. As the only technology with diagnostic and therapeutic capabilities that is suitable for flight, the development of ultrasound applications for the space program will directly benefit people on Earth and vice versa. In this presentation, I will discuss my past and current work in three main areas of ultrasound diagnostics and therapeutics including: controlled soft tissue fractionation; bubble-based ultrasound imaging; and pulsed focused ultrasound for musculoskeletal injuries that could be used for a variety of conditions found both on Earth and in space. In all three focus areas, a deep theoretical approach along with experimentation will be used to progress these applications to clinical implementation while considering how the unique environment in space will influence the transition to flight.
