摘要

空气涡轮机通常用于振荡水柱(OWC)装置中进行波浪能转换。本文的目的是通过在Fluent®中实现执行器磁盘模型(ADM)来模拟OWC涡轮机的性能。在二维数值波槽中建立了一套不同规则波试验。利用井式水轮机风洞试验分析的信息对模型进行了验证。在所有情况下,压降和气流都实现了线性响应,有效地证明了执行器盘模型适用于OWC装置。

Numerical simulation of a simple OWC problem for turbine performance

Air turbines are commonly used in Oscillating Water Column (OWC) devices for wave energy conversion. The purpose of this paper is to simulate the performance of an OWC turbine through the implementation of an Actuator Disk Model (ADM) in Fluent®. A set of different regular wave tests are developed in a 2D numerical wave flume. The model is tested using the information analysed from experimental tests on a Wells type turbine, carried out in wind tunnel. Linear response is achieved in terms of pressure drop and air flow in all cases, proving effectively the actuator disk model applicability to OWC devices.
