Abstract:

A common problem that affects the continuous casting process is the formation of a sink funnel or a vortex funnel in the end of the teeming process of a steel ladle. This causes the slag to be carried over with the molten steel to the tundish, generating inclusions in the produced steel ingot. In this work we propose an innovative device designed to delay the sink-funnel formation and hence decrease the critical draining height. The apparatus consists of an air-suctioning spear that induces a reduced pressure gradient just above the slag/air interface, in a position vertically alignedwith the

Abstract:

The problem of the coating of steel has been considered in several Mathematics in Industry study groups. In this process, after passing through a bath of molten alloy, steel sheeting is drawn upward to allow draining under gravity and stripping using an air knife, leaving a coating of desirable thickness. Here we discuss some aspects of the problem and in particular the gravity draining component. The problem is a very nice introduction to industrial modelling for students, but is also relevant for manufacturing. References Elsaadawy, E. A., Hanumanth, G. S., Balthazaar, A. K.

This study delves into mitigating the formation of an air-core vortex, a common occurrence during liquid drainage in tanks, known to impede the draining process and potentially decrease the tank's efficiency and longevity. The research explores passive measures to control the emergence of this vortex. Computational fluid dynamics simulations using OpenFOAM were employed to investigate the impact of two distinct geometries, a disc plate and a cone on the formation of the air-core vortex during liquid drainage. Various drainage behaviours were observed and the changes of the draining process can

Abstract:

We theoretically considered two-dimensional flow in a vertically aligned thick molten liquid film to investigate the competition between cooling and gravity-driven draining, which is relevant in the formation of metallic foams. Molten liquid in films cools as it drains, losing its heat to the surrounding colder air and substrate. We extended our previous model to include non-isothermal effects, resulting in coupled non-linear evolution equations for the film’s thickness, extensional flow speed and temperature. The coupling between the flow and cooling effect was via a constitutive relationship

Immense information and details observation of flow physics inside a draining tank can be achieved by adopting reliable numerical simulations. Yet the accuracy of numerical results has been always debatable and it is mainly affected by the grid convergence error and computational modeling approaches. Hence, this study is divided into two stages. In the first stage, this paper determines a systematic method of refining a computational grid for a liquid draining inside a tank using OpenFOAM software.

This research simplifies this complex formulation by neglecting the inertial term, thus the Bernoulli’s equation can be used. Results show how the inertial

Abstract:

Introduction. It has been established that porous draining asphalt concrete (DAC) is an open-frame asphalt concrete that is specially designed with a high content of air voids, which are designed to remove water from the surface of the road surface. Pavement surfaces that include draining asphalts, permeable wear courses, and porous asphalt pavements are gaining more and more acceptance in the road industry worldwide. Drainable asphalt can be susceptible to freeze-thaw damage in cold climates and will require winter maintenance practices. The service life of such coatings varies greatly depend

RESUMOOs tubos torácicos são inseridos no espaço pleural a fim de drenar ar ou líquido. Pelo fato de que a pressão pleural é em geral negativa, pelo menos durante uma parte do ciclo respiratório, foi desenvolvido o sistema de drenagem pleural fechado para evitar que o ar atmosférico penetre no espaço pleural, mas ao mesmo tempo permita que o ar e o fluído drenem continuamente para fora do espaço pleural. A drenagem de tórax é um procedimento simples, porém, um grande número de pacientes a ele submetidos, apresenta complicações relacionadas à falhas do sistema, em geral, devido a desconheciment

Abstract BACKGROUND. The infraorbital recess of the maxillary sinus can reach in front of the nasolacrimal duct to become prelacrimal recess. During a routine Cone Beam CT (CBCT) study of a male patient of 72 years old, there were bilaterally found infraorbital maxillary air cells (IMACs) resulted after the almost complete closure of infraorbital recesses of the maxillary sinuses. Only that on the left side was reaching in front of the nasolacrimal canal.

Abstract:

Air valves operate as protection devices in pipelines during drainage processes in order to mitigate vacuum pressures and control the transient flows. Currently, different authors have proposed one-dimensional models to predict the behaviour of orifices during filling and draining events, which offer good numerical results. However, the three-dimensional dynamic behaviour of air-admission orifices during drainage processes has not been studied in depth in the literature. In this research, the effects of air inflow on an orifice installed in a single pipe during drainage events are analysed usi

This article is devoted to the equipment for gas-dynamic spraying in order to simplify its design, to provide the possibility of adjusting the parameters (temperature, pressure, speed, ejection) of the air-polymer flow, and to clarify the fundamental possibility of creating polymer functional coatings with gas-dynamic spraying. The polymeric materials, depending on their brand, are completely inert and do not react in any chemical reaction with food, animal waste products, acids and other corrosive media. It is known that polymeric materials can be attributed to the two main classes of reactan

Abstract:

Abstract: This research paper addresses the issue of excess ash content in CFBC boilers when lower quality fuel, such as the lower or upper layer of lignite, is supplied. The increase in ash content leads to the continuous draining of bed ash and often results in the restriction of bed material flow in the furnace inlet pipe to the slag cooler. While this may not have a significant impact on the required load in normal conditions, it can severely affect the unit's load capacity in the case of poor-quality coal. The paper proposes a solution for waste slag management using air blasters in 135 M

Abstract:

Inertial models have been used by researchers to simulate the draining and filling processes in water pipelines, based on the evolution of the main hydraulic and thermodynamic variables. These models use complex differential equations, which are solved using advanced numerical codes. In this study, a quasi-static flow model is developed to study these operations in hydraulic installations. The quasi-static flow model represents a simplified formulation compared with inertial flow models, in which its numerical resolution is easier because only algebraic equations must be addressed.
