Abstract Pursuant to implementation of a new mechanical engineering curriculum at Clemson University, results of the new introductory course in thermal-fluid science are presented. This course is situated in the second semester of the sophomore year for mechanical engineering majors, and is a prerequisite for the subsequent courses in thermodynamics and fluid mechanics. In addition to introducing thermodynamic property analysis, the course develops conservation laws for mass, momentum, and energy and provides an emphasis in design. Discussion is presented of the motivation, placement in the overall curriculum, interaction with other curriculum elements, and the selection of textbooks.

The Lunar Penetrating Radar (LPR) onboard the Yutu-2 rover from China’s Chang’E-4 (CE-4) mission is used to probe the subsurface structure and the near-surface stratigraphic structure of the lunar regolith on the farside of the Moon. Structural analysis of regolith could provide abundant information on the formation and evolution of the Moon, in which the rock location and property analysis are the key procedures during the interpretation of LPR data. The subsurface velocity of electromagnetic waves is a vital parameter for stratigraphic division, rock location estimates, and calculating the rock properties in the interpretation of LPR data. In this paper, we propose a procedure that combines the regolith rock extraction technique based on local correlation between the two sets of LPR high-frequency channel data and the common offset semblance analysis to determine the velocity from LPR diffraction hyperbola. We consider the heterogeneity of the regolith and derive the relative permittivity distribution based on the rock extraction and semblance analysis. The numerical simulation results show that the procedure is able to obtain the high-precision position and properties of the rock. Furthermore, we apply this procedure to CE-4 LPR data and obtain preferable estimations of the rock locations and the properties of the lunar subsurface regolith.
