Hydraulic particulars

In the paper "Assessment of the dynamic impact of debris flow on structure safety: A case study of check dam in Vietnam" the stability of a check dam located in Vietnam is re-evaluated in two regimes of the debris flow impact: (i) static impacts as conventional flood flow and (ii) dynamic impacts adopting Huebl’s approach. The results help to analyze shortcomings of the current design procedure applied for checking dams in particular and hydraulic structures in general.

Ebook "Modelling water flow in unsaturated porous media: Accounting for nonlinear permeability and material heterogeneity" focuses on two issues related to mathematical and numerical modelling of flow in unsaturated porous media. In the first part numerical solution of the governing equations is discussed, with particular emphasis on the spatial discretization of highly nonlinear permeability coefficient. The second part deals with large scale flow in heterogeneous porous media of binary structure.

The goal of this study is to demonstrate and quantify the impact that the uncertainty in thermophysical properties has on key metrics of thermal hydraulic importance for MSRs, in particular on the heat transfer coefficient. In order to achieve this, computational fluid dynamics (CFD) simulations using the RANS k-ω SST model were compared to published experiment data on molten salt.

The most mechanized agricultural operations include a tractor as a primary power unit, even though the tractor itself is not particularly useful without an implement attached. Innovations and efficiency improvements in tractor engines, powertrains, and auxiliary power systems have been ongoing since tractors were invented a century ago and significant gains have been realized. However, PTO and hydraulic power systems are well established and effective for today‟s applications, the search for more versatile and efficient power transfer continues.
