This study numerically analyzes a submerged horizontal plate (SHP) device subjected to both regular and irregular waves. can be used either as breakwater or wave energy converter (WEC). The WaveMIMO methodology was applied for the numerical generation propagation of sea state Rio Grande coast in southern Brazil. finite volume method employed solve conservation equations mass, momentum, fraction transport. fluid model handle water-air mixture. SHP length (Lp) effects were carried out five...
This study describes the validation and verification of a two-dimensional numerical wave channel with Submerged Horizontal Plate (SHP). The SHP is fixed, submerged structure dual function: it acts as breakwater energy converter. To carry out procedures for computational modeling, experimental results obtained from literature were used. A relative error 2.14% maximum axial velocity below was in validation, while an average absolute 0.0043 m/s variation identified verification. Therefore, can...
In this work it is numerically studied the wave flow inside a tank and main operational physical principle of three different energy converters (WEC): oscillating water column (OWC), overtopping submerged plate. The are evaluated in laboratory real scales. For all cases conservation equations mass, momentum one equation for transport volumetric fraction solved with finite volume method (FVM). To tackle water-air mixture, multiphase model Volume Fluid (VOF) used. Several results showed...
The need for clean and renewable energy sources has nowadays contributed to give relevance the study of sea wave energy. In this context, present work brings a computational modeling analyze fluid-dynamic behavior submerged plate converter. Basically, its operating principle consists in passage waves through horizontal plate, generating flow under it where turbine is placed, converting mechanical into electrical numerical model uses software GAMBIT FLUENT. latter, which based on finite...
The present work applies Constructal Design to study numerically a fin-cavity system under mixed convection flow. is composed of heat triangular fin inserted in squared cavity. flow driven by the superior wall (lid) displacement. main purpose effect geometry and area ratio ( φ ) over dimensionless convective transfer coefficient (Nusselt number). Rayleigh Ra H Reynolds Re numbers thermal performance optimal geometries also evaluated. For all cases Prandtl number constant Pr = 0.71)....
The high availability of energy within ocean waves is seen as an important and abundant alternative a renewable source. This paper presents numerical study the submerged horizontal plate type wave converter, assessing its theoretical efficiency for several relative heights. propagation incidence distinct periods through device structure were simulated, was evaluated disregarding presence turbine under plate. A total six between 1.25 3.50 s with height 0.06 m considered different results...
Este trabalho apresenta um estudo numerico de uma aleta triangular inserida em cavidade placa superior movel e submetida a escoamento por conveccao mista. O objetivo maximizar transferencia calor entre o para diversas configuracoes da aleta, bem como, analisar efeito do numero Reynolds sobre geometria otima. Foram avaliados escoamentos com quatro diferentes numeros Reynolds: Re= 10, 10², 5×10² 10³. Prandtl Rayleigh foram mantidos fixos: Pr = 0.71 Ra HH= 104, respectivamente. Nusselt medio...
A grande concentração de energia disponível nas ondas do mar faz desse recurso uma importante alternativa como fonte renovável. O sistema placa horizontal submersa é estrutura utilizada quebra-mar, mas pode ser utilizado, também, conversor das ondas. objetivo deste estudo simular, numericamente, o tipo em escala real e analisar a similaridade dos resultados com relação precedentes um modelo laboratório, forma possibilitar recomendações teóricas sobre geometria conversor. Para isso, as...
Os oceanos concentram uma grande quantidade de energia, disponível, principalmente, nas ondas do mar, fazendo desse recurso importante alternativa como fonte energia limpa e renovável. O sistema placa horizontal submersa é um tipo estrutura utilizada quebra-mar pode ser utilizado, também, conversor das ondas. objetivo deste estudo analisar numericamente o efeito da variação conjunta comprimento altura relativa sobre a sua eficiência conversão, bem comportamento escoamento que ocorre abaixo...
Diversos estudos apontam que em pouco tempo a capacidade de geração energia atual bem como forma é obtida não será suficiente para suprir demanda global. Em virtude deste déficit se projeta o futuro, as fontes renováveis estão evidência. A Terra possui uma ampla extensão litorânea onde contida nas ondas do mar encontra-se disponível e apresenta um elevado potencial energético, sendo fonte limpa totalmente renovável. Entre os diferentes dispositivos conversão das elétrica, mais promissores...
