The aim of this paper is to study the local Nusselt number of the symmetrical liquid-liquid jets emitting from a nozzle. Equations obtained from theoretical works are arranged in the form of a computerized model. The validity of this model was tested by the data from an experimental paper [1]. After few adjustments the model predicted the experimental data with a reasonable accuracy. Making sure of the model acceptable operation the effects of changes of hydrodynamic and thermal parameters on local Nusselt number were investigated which eventually lead to an equation for predicting numerical values of local Nusselt number as a function of liquid jet length.
