A novel approach is presented to predict wind pressure on tall buildings for early-stage generative design exploration and optimisation. The method provides instantaneous surface pressure data, reducing performance feedback time whilst maintaining accuracy. This is achieved through the use of a machine learning algorithm trained on procedurally...

This work involves the application of adaptive hierarchical grids to free surface Navier-Stokes simulation of viscous waves in a stationary tank and their interaction with a cylinder. Adapting quadtree grids are combined with a volume of fluid (VoF) approach, in which a high resolution interface capturing scheme is used for advection of the...

In the present study, the surface tension is introduced as volume forces according to the continuum surface force (CSF) model [1] using the surface tension coefficient and the mollified volume fraction (color) function. The latter can be taken in the first approximation as the volume fraction defined numerically due to (possible) smoothing of...

A surface capturing method is developed for steady water-air flow with gravity. Second-order accuracy is obtained with flux limiting and turbulence is modeled with Menter's model. The model is solved efficiently with a combination of multigrid and defect correction. Results for two test cases confirm the efficiency and accuracy of the method.

Many authorities have supported the concept of integrated working or partnering. They claim a number of advantages of partnering such as greater co-operation, cost savings, timely completion of projects and improved quality but there remain a number of difficulties both at a theoretical and practical level. These difficulties manifest themselves...

The paper concerns the potential of sensors as architectural design tools in different spatial and temporal scales. In particular, the focus is on how sensors are able to operate in a constantly changing environment, and how sensors might nurture an intuition of otherwise non perceivable aspects of performance within architecture.The study...

The contribution deals with numerical solution of a complex problem of aerodynamic loads evoked by a train motion while entering and passing through a double track tunnel. The train set consists of an electrical loco and three coaches. The loco model shape closely corresponds with a real three-system electrical locomotive developed and produced...

Using direct numerical simulations of Rayleigh-B\'enard convection (RBC), we perform a comparative study of the spectra and fluxes of energy and entropy for large and infinite Prandtl numbers in two (2D) and three (3D) dimensions. We observe close similarities between the 2D and 3D RBC, in particular the kinetic energy spectrum $E_u(k) \sim k^{...

Differently to Kolmogorov's second similarity hypothesis, we find that the 2n-th order velocity and scalar structure functions scale with n-th order moment of the energy dissipation and the scalar dissipation, respectively. The origins of this scaling are analyzed by the transport equations of the fourth order velocity and scalar increment...

Research to the failure mechanism piping (internal, backward erosion) in the Netherlands shows that the dikes require costly berms to meet the required safety standards. According to the Sellmeijer piping-formula, the d70 (70%-quantile of the grain size distribution by weight) is an important parameter in the resistance against piping. Therefore...

In many geotechnical projects, field data is used to determine the soil parameters. In most instances, however, the statistical analysis is performed ad hoc and the spatial distribution of this data is not (expclitly) accounted for. A more formal statistical approach allows to make better use of the data and combine it in a consistent manner...

The purpose of the present study is to explore and validate the efficiency and accuracy of the predictive capability of CFD models for fully developed natural fires in large compartments. The FDS CFD software was used to simulate three large-scale fire tests. The fire tests (nine in total) had been carried out in 1993 at Cardington UK, in...

In this paper we suggest some algorithms for the fluid-structure interaction problem stated using a domain decomposition framework. These methods involve stabilized pressure segregation methods for the solution of the fluid problem and fixed point iterative algorithms for the fluid-structure coupling. These coupling algorithms are applied to the...

The water from rainfall that may be retained in the soil or the surface can seep by gravity or capillary action and will form the underground phase of the hydrologic cycle. Permeability measures the greater or lesser ease each soil, when saturated, offers the piping of water through its interstices. The permeability depends mainly on the...

A novel chemical self-healing system based on microcapsule technology for cementitious composites is established in Guangdong Key Laboratory of Durability for Coastal Civil Engineering, Shenzhen University. The key issue of this system is how to release the healing material and how to activate the healing mechanism. In this paper, the study is...
