Length and time scales of response of sediment suspensions to changing flow conditions (2011)
Journal Article
Dorrell, R. M., & Hogg, A. J. (2012). Length and time scales of response of sediment suspensions to changing flow conditions. Journal of Hydraulic Engineering, 138(5), 430-439. https://doi.org/10.1061/%28asce%29hy.1943-7900.0000532

Turbulent suspensions of sediment are investigated to establish the characteristic length and time scales on which they adjust from one state to another. The suspensions are modeled by using a simple closure for the turbulent fluctuations in which th...

Evaluation of external heat loss from a small-scale expander used in organic Rankine cycle (2011)
Journal Article
Li, J., Pei, G., Li, Y., & Ji, J. (2011). Evaluation of external heat loss from a small-scale expander used in organic Rankine cycle. Applied thermal engineering, 31(14-15), 2694-2701. https://doi.org/10.1016/j.applthermaleng.2011.04.039

With the scaling down of the Organic Rankine Cycle (ORC), the engine shaft power is not only determined by the enthalpy drop in the expansion process but also the external heat loss from the expander. Theoretical and experimental support in evaluatin... Read More about Evaluation of external heat loss from a small-scale expander used in organic Rankine cycle.

Construction and dynamic test of a small-scale organic rankine cycle (2011)

The structure of the deposit produced by sedimentation of polydisperse suspensions (2011)
Journal Article
Dorrell, R. M., Hogg, A. J., Sumner, E. J., & Talling, P. J. (2011). The structure of the deposit produced by sedimentation of polydisperse suspensions. Journal of Geophysical Research: Earth Surface, 116(F1), https://doi.org/10.1029/2010jf001718

To interpret the deposits from particle-laden flows it is necessary to understand particle settling at their base. In this paper a quantitative model is developed that not only captures how particles settle out of suspension but also the composition...
