Lu, Suli (author), Liu, Jialun (author), Hekkenberg, R.G. (author)A good mesh is a prerequisite for achieving reliable results from Computational Fluid Dynamics (CFD) calculations. Mesh properties include mesh types, computational domain sizes, and node distributions. However, in literature, we found no clear consensus about what these properties should be. In this article, we performed a case study on ship...journal article 2021

Lu, Nan You (author), Manuel, Lance (author), Hawbecker, Patrick (author), Basu, S. (author)Thunderstorm downbursts have been reported to cause damage or failure to wind turbine arrays. We extend a large-eddy simulation model used in previous work to generate downburst-related inflow fields with a view toward defining correlated wind fields that all turbines in an array would experience together during a downburst. We are also...journal article 2021

Lu, T. (author), Li, Z. (author), Huang, H. (author)Shrinkage-induced cracking can impair the durability of concrete structures. In the past few decades, this topic has drawn more and more attention. Shrinkage of mortar and concrete is actually the result of the interaction between the shrinking cement paste and the non-shrinking aggregates. In recent years, different models that consider the...journal article 2021
