In modelling physical models used k-epsilon and active energy. the material used is only one phase, namely water. Temperature normal seawater set 30? and temperature discharge outlet 37?. The boundary conditions are discharged outlets, ambient inlet, outlet, ocean, seabed and seashore. The discharge outlet is the discharge area of the cooling water power plant modelled as an inlet velocity with a velocity of 1.71 m \/ s and a temperature value of 37?, the ambient inlet boundary condition is modelled as an inlet velocity at 0.4 m \/ s and a temperature value of 30?. <img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/9edc2979-8861-4fd4-a555-aa3b00b793ff\/61f88302-4dba-4eb7-9d04-aa3b00bbefca_bismillah.jpg?width=690&amp;upscale=false\" alt=\"boundary conditions\">Outlet modelled as outflow.
