  • Hughes, Jessica; Krebs, Eric J.; Roundy, David (American Institute of Physics, 2013-01-14)
    We develop a classical density functional for water which combines the White Bear fundamental-measure theory (FMT) functional for the hard sphere fluid with attractive interactions based on the statistical associating fl ...
  • Kustusch, Mary Bridget; Roundy, David; Dray, Tevian; Manogue, Corinne (American Institute of Physics, 2013-01)
    Several studies in recent years have demonstrated that upper-division students struggle with partial derivatives and the complicated chain rules ubiquitous in thermodynamics. We asked several experts (primarily faculty ...
  • Roundy, David; Rogers, Michael (American Association of Physics Teachers, 2013-01)
    We describe an upper-division experiment in thermal physics where students measure the tension of a rubber band as a function of temperature and length, and use a Maxwell relation to find the change in internal energy ...
  • Krebs, Eric J.; Schulte, Jeff B.; Roundy, David (American Institute of Physics Publishing, 2014-03-28)
    We present a modification to our recently published statistical associating fluid theory-based classical density functional theory for water. We have recently developed and tested a functional for the averaged radial d ...
  • Roundy, David; Kustusch, Mary Bridget; Manogue, Corinne (American Association of Physics Teachers, 2014-01)
    We introduce a series of activities to help students understand the partial derivatives that arise in thermodynamics. Students construct thought experiments that would allow them to measure given partial derivatives. The ...
  • Kustusch, Mary Bridget; Roundy, David; Dray, Tevian; Manogue, Corinne A. (American Physical Society, 2014-01-10)
    Several studies in recent years have demonstrated that upper-division students struggle with the mathematics of thermodynamics. This paper presents a task analysis based on several expert attempts to solve a challengin ...
  • Schulte, Jeff B.; Kreitzberg, Patrick A.; Haglund, Chris V.; Roundy, David (2012-12-28)
    We investigate the value of the correlation function of an inhomogeneous hard-sphere fluid at contact. This quantity plays a critical role in statistical associating fluid theory, which is the basis of a number of recen ...
