For each ε value, we have compared the experimental and numerical results in terms of the free surface profiles and the phase speeds to give recommendations for the solitary wave solution and the generation methodology that demonstrates the best performance. Numerical modeling is done within a Smoothed Particle Hydrodynamics (SPH) framework developed in Valizadeh and Rudman (2017). In the present study, the two solitary wave generation methodologies, namely, Goring's Method (GM) and the Malek-Mohammadi and Testik Method (MMTM), described in Goring (1979) and Malek-Mohammadi and Testik (2010) respectively, have been used to examine the solitary wave solutions of Boussinesq, Rayleigh, Grimshaw and Fenton, both experimentally and numerically for three different relative wave height (ε), ratios of 0.1, 0.3 and 0.6. Such waves give a better description of the target wave amplitude, has minimal amplitude dissipation during propagation and has negligible trailing waves. Also, make sure that those filters' outputs are pushing the same directions as the top wavemaker.The generation of stable and pure solitary waves in large-scale experimental flumes and numerical models is the focus of this study. This way you can continue that circular motion in your tank. If you have two filters with intakes on both sides, then it doesn't really matter which way you put your wavemakers as long as one one one side is at the top and the other on the other side is at the bottom. So, using the same logic as before, as the water gets pushed across the top towards the right side it is going to catch the second wavemaker and that wavemaker is going to push it across the bottom back towards the left.įurthermore, this bottom wavemaker is going to help push any detritus that is laying on the top of your substrate towards the left side where your filter intakes are placed. The second wavemaker is going to go on the right side of your tank but thing time along the bottom. ![]() If you have two wavemakers, they should also be placed strategically. Your filters' outputs at the top of your tank should also be facing the same direction as your wavemaker to help push that top tank water over to the right side. This would make sure that all the water is in a continuous circular motion in the tank and it is going to help carry the detritus along the bottom towards the intake. It is returned to the wavemaker from the bottom of your tank so what is coming back to the wavemaker along the bottom from right to left is also going to hit your filter intake that is one the bottom left side. Now, since the intake strainer is at the bottom of the tank and it is already said that a wavemaker's best position is gonna be on the top of the tank to create a surface aggregation therefore your wavemaker is also going to go on the left side of the tank along with your filter intake.Īs water is pushed across the top of your tank from left to right. Let's say you are looking at the tank and your filter intake is placed at the left side of the tank. ![]() The first thing you want to do is make sure that you position it high enough in the tank so that when you angle it upwards it can break the surface tension and create waves. This surface agitation is going to allow the transfer of oxygen into the water. So, let's start with the assumption that you only have one wavemaker and one filter. Where to place a wavemakerĭetermining which side of the tank is best for your wavemaker depends on which side of the tank your filter intake is on. The wavemaker can create a circular pattern of water flow in your tank to avoid any dead spots, kind of creating a vortex in your tank if your wavemaker is placed correctly. ![]() The flow and pressure of the wavemaker keep the fishes preoccupied and not so focused on each other. Calming AggressionĪ wavemaker can also help to calm the aggression in aggressive fishes like in African Cichlids. So, wavemaker is going to help oxygenate your water just like those bubbles and if possible even more by constantly breaking a large portion of the surface tension. Only when they reach the surface and the bubbles pop and break the surface tension is when the transfer of oxygen happens. It does the same work as the bubbler or air stone and much more.Īs the bubbles rise to the top of your aquarium, they are not oxygenating your water. Wavemaker in an aquarium is a great tool with numerous benefits. ![]() Edit Successfully updated! Wavemaker: where to place a wavemaker in the tank
