Approximation of the cooling effects of water nozzles by mathematical functions

The Bachelor thesis deals with a cooling process of full cone water nozzles. It explains the principle of the continuous steel casting which these nozzles are used for. The basics of heat transfer and spray cooling are also described. The thesis then summarizes the way of the experiment with these nozzles. The purpose of the thesis is to choose an appropriate 3D mathematical function which would well characterize the distribution of the heat transfer coefficient under the nozzle and then create an algorithm for finding its parameters. The algorithm is programmed in MATLAB and implemented on the data gained by the experimental way for two types of full cone water nozzles
