      Determining true material constants of semisolid slurries from rotational rheometer data 

      Alexandrou, Andreas N.; Georgiou, G. C.; Economides, E. A.; Modigell, M. (2016)
      In this work we revisit the issue of obtaining true material constants for semisolid slurries. Therefore, we consider the circular Couette flow of Herschel-Bulkley fluids. We first show how true constants can be obtained ...

      Nonanticipative transmission for sources and channels with memory 

      Kourtellaris, C. K.; Charalambous, Charalambos D.; Boutros, J. J. (Institute of Electrical and Electronics Engineers Inc., 2015)
      In this paper we analyze nonanticipative (delayless) transmission of source symbols with memory over channels with memory (with and without feedback). We employ duality of source, channel pairs with respect to distortion ...

      On the transition to turbulence of a viscoplastic fluid past a confined cylinder: A numerical study 

      Kanaris, N.; Kassinos, Stavros C.; Alexandrou, Andreas N. (2015)
      Three-dimensional direct numerical simulations of a Bingham fluid flowing past a confined circular cylinder have been used in order to investigate viscoplastic effects in the wake-transition regime. The case of a cylinder ...
