Abstract
In this work, we use computational fluid dynamic simulation tools for investigation two dimensional of eel movement. Firstly, the numerical study of smooth particle hydrodynamics was applied for determination drag coefficient and lift coefficient of undulation movement eel body. The initial mesh was manual. So, the effective parameters of eel movement were investigated. The smooth particle hydrodynamic method was not use, because of saving on time. Therefore, fluent software was used. UDF were added to the fluent software, which it can be move the boundary layer of mesh with eel movement. The dynamic mesh tools of fluent software were used. Initial shape had a curvature and utilized for...

Abstract
In the present study, the objective was to obtain the forward and backward swimming equation for the fiery eel and the European Eel in the experimental section. Then, by processing the videos, swimming equations were extracted. The obtained equations were used to move the 3D eel geometry of the STAR-CCM + software. The purpose of numerical modeling is to study the effect of body amplitude and wave frequency on the forces applied on the eel body during swimming. Numerical simulations were performed for the three amplitudes of 0.1, 0.115, and 0.138m and four different frequencies of 1, 1.2, 1.2 Hz, and Reynolds number 3857. The results of numerical work show us that the increase in the wave...
