  The water flow enters the supercritical state after passing over the overflow, which is accompanied by high and destructive energy for downstream facilities and natural features. Consumables are used to control this energy. The most common and almost a permanent and widely used member of energy consuming facilities is the relaxation pool. These pools form a hydraulic jump at a specific distance, which is the length of the pool, to deplete the jump energy and thus flow. The pond, with the help of its accessories, does this, which are called calming blocks. Different types of these blocks have been used that in recent research, the use of even or continuous continuous or single wall or the use of even or single perforated wall has had better results. Therefore, in this research, using FLOW 3D software, we have attempted to simulate the simultaneous use of a continuous wall and a perforated wall to design a pond with a shorter length, resulting in cost depreciation.

  When water enters the tondab, it goes fast and has a high speed at the bottom of the tandab. So that the current becomes supercritical and has destructive kinetic energy. Therefore, in order to maintain the natural effects downstream of overflows, including rivers and dams, this energy must be consumed. To achieve this, researchers have sought to create energy dissipators. Among them are relaxation pools. The mechanism of relaxation pool is such that it creates a hydraulic jump in a short distance and then from contact with existing accessories such as calming blocks, just walls, perforated walls to wear out. The energy from the tornado and then the hydraulic jump will help. Many people have tried to use perforated and continuous walls individually or in pairs with different flow conditions and geometric dimensions. Therefore, we decided to control the hydraulic jump by examining the simultaneous use of a pair of perforated and continuous walls with the aim of 1- reducing the secondary depth 2- relative energy loss. For this purpose, by software modeling, a continuous wall with dimensions of 80*13*1 cm and a perforated wall with dimensions of 80*7*1 cm with an optimal distance in FLOW 3D software have been investigated. The result was that using a perforated wall and a continuous wall wasted more energy than other scenarios. Manuscript profile
