Temperature fields were measured below two parallel, rectangular air nozzles. These are the types of nozzles that are commonly used in the melt-blowing process to produce fine polymer fibers. Each rectangular nozzle had a large length-to-width ratio, and the nozzles were closely spaced. Three types of nozzles were compared: (1) a die where the jets meet at a 60° angle and the die tip was blunt, (2) a die with a 60° angle and a sharp tip, and (3) a die with a 70° angle and a sharp tip. Correlations were developed to predict the temperature fields below these die types.
