The aim of this work is to analyse the formation mechanisms large-scale coherent structures in flow around a wall-mounted square cylinder, due their impact on pollutant transport within cities. To end, we assess causal relations between modes reduced-order model obtained by applying proper-orthogonal decomposition high-fidelity-simulation data case under study. are identified using conditional ...

Hydrogen refueling stations are one of the key infrastructure components for hydrogen-fueled economy. Skid-mounted hydrogen (SHRSs) can be more easily commercialized due to their smaller footprints and lower costs compared stationary stations. The present work modeled explosions in a skid-mounted station predict overpressures hydrogen-air mixtures investigate protective effects different explos...

Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...

this paper presents a new methodology for the automated inspection of pipes. standard inspection systems are based on closed-circuit television cameras which are mounted on remotely controlled robots and connected to remote video recording devices. the main problems of such camera-based inspection systems are: 1) the lack of visibility in the interior of the pipes and 2) the poor quality of the...

A brief review of large eddy simulation (LES) applications for different bluff-body flows performed by the author and his co-workers is presented. Examples of flows range from simple cube flows characterized by sharp edge separation over a three-dimensional hill where LES relies on good near-wall resolution, to complex flows of a tall, finite cylinder that contains several flow regimes that cau...

Consider a graph G with |V (G)| = p and |E(G)| q let f : V (G) → {k, k + 1, 2, . − 1}} be an injective function. The induced edge labeling ∗ for vertex is defined by (e) all e uv ∈ E(G) bijective. If f(V (G)) ∪ {f E(G)} , 1}, then called k-super cube root mean labeling. such exists, graph. In this paper, I introduce prove the existence of to graphs viz., triangular snake Tn, double D(Tn), Quadr...

We classify the Deligne-Mumford stacks M compactifying moduli space of smooth $n$-pointed curves genus one under condition that points represent Gorenstein with distinct markings. This classification uncovers new spaces $\bar{\mathcal{M}}_{1,n}(Q)$, which we may think coming from an enrichment notion level used to define Smyth's $m$-stable spaces. Finally, construct a cube complex Artin interpo...
