Numerical Modeling of the Thermodynamic Effects of Sea Waters on the Corrosion in Coastal and Offshore Structures in the South of Iran

However, several factors affect the corrosion of a marine structure. Investigating each of the factors involved in the corrosion of a structure in the environmental conditions of sea water is very difficult and complex, and each of the researches that have been carried out on the corrosion of these structures, often on one type of corrosion and also on one or more metals and or alloy is done. In this research, the monthly changes of sea surface temperature and sea surface, as two important properties of sea water, have been studied using the MITgcm model, which is a three-dimensional and non-linear model, with the most accurate bathymetric data and with a spatial accuracy of 2 minutes. For this purpose, the data of temperature, salinity, evaporation rate minus precipitation, wind, net heat flux with a time accuracy of one month and a spatial accuracy of one degree were introduced to the model as initial data. The results of the last year of modeling show that the highest values of sea surface salinity (SSS) at the value of 37.3 PSU and sea surface temperature (SST) at the value of 32.2 degrees Celsius occur in the summer season near the southern coast of Iran. On the other hand, the intensity of winds in the Arabian Sea is higher in the summer season than in other seasons of the year, and the intensity of the surface currents is also higher.
