Isothermal Calorimetry Study of Blended Cements and its Application in Numerical Simulations

Xiong, X. (author), Van Breugel, K. (author)

Apparent activation energy (E) is generally used to consider the effect of temperature on the kinetics of cement hydration in the numerical simulation of cement hydration processes. This paper deals with an experimental study on the kinetics of Portland cement and blast furnace slag cement using isothermal Calorimetry at 20, 30, and 40°C. Two...

A Data-Driven Surrogate Approach for the Temporal Stability Forecasting of Vegetation Covered Dikes

Jamalinia, E. (author), Sadeghi Tehrani, F. (author), Steele-Dunne, S.C. (author), Vardon, P.J. (author)

Climatic conditions and vegetation cover influence water flux in a dike, and potentially the dike stability. A comprehensive numerical simulation is computationally too expensive to be used for the near real-time analysis of a dike network. Therefore, this study investigates a random forest (RF) regressor to build a data-driven surrogate for a...

Error Features in Predicting Typhoon Winds: A Case Study Comparing Simulated and Measured Data

Peng, Shaoyuan (author), Liu, Y. (author), Li, Renge (author), Wei, Ying (author), Chan, Pak Wai (author), Li, Sunwei (author)

Simulating a typhoon’s wind field via mesoscale models is important in terms of providing not only the guidelines for urban planning and onshore/offshore constructions, but also the provision of insight into the dynamics and thermodynamics of tropical cyclone systems. Therefore, the errors that are contained in simulation results were...

Dryland avulsion sequences: Insights from data-model comparison of a terminal dryland river system

Karamitopoulos, P. (author), Donselaar, M.E. (author), Weltje, G. J. (author), van Toorenenburg, K. A. (author)

An advection–diffusion model of fluvial processes was used to analyze the stratigraphic expression of avulsions in terminal river systems and understand their control on basin-fill architecture. The initial and boundary conditions of the model runs (i.e., catchment area, smoothed initial topographic surface, grain-size distribution and...

Influence of solder condition on effective thermal conductivity of two-directional random fibres: Pore-scale simulation

Xiao, Tian (author), Zhang, Qiaoling (author), Yang, Xiaohu (author), Hooman, K. (author), Li, Guodong (author)

It is indicated that the solder joint of the metal fibrous materials is a critical factor impacting the heat conduction. To reveal the mechanism by which solder joint sizes, solder joint skips, solder flux materials, and filling media affect the thermal conductivity of fibres, pore-scale numerical simulation is employed to study the thermal...

Optimization of vascular structure of self-healing concrete using deep neural network (DNN)

Wan, Z. (author), Chang, Z. (author), Xu, Y. (author), Šavija, B. (author)

In this paper, optimization of vascular structure of self-healing concrete is performed with deep neural network (DNN). An input representation method is proposed to effectively represent the concrete beams with 6 round pores in the middle span as well as benefit the optimization process. To investigate the feasibility of using DNN for...

The dependence of speckle contrast on velocity: A numerical study

van As, K. (author), Simons, Bram A. (author), Kleijn, C.R. (author), Kenjeres, S. (author), Bhattacharya, N. (author)

We study how the speckle contrast depends on scatterer velocity, with the goal of further developing laser speckle imaging as a quantitative measurement technique. To that end, we perform interferometric computer simulations on a dilute plug flow. The results of our numerical experiment, that we compare with known analytical expressions to...
