Details
This DIN SPEC establishes a procedure for the characterization of industrial sprays and accordingly, the drops or wetted particles that form the spray. For this purpose, guidelines for the measurement of sizes of spherical drops or nearly spherical drops have been defined. In such cases, the drop size is solely defined by the diameter. The DIN SPEC includes requirements about the necessary spatial resolution of the employed technique. Furthermore, guidelines for the acquisition of drop velocities and the related mass flux densities are provided. Beyond that, recommendations for the acceptable uncertainty of the measurement results are given. This DIN SPEC is valid for applications, where the drop diameters are in the range of approx. 1 µm to 1 mm. It can be employed for sprays formed by transparent drops as well as sprays formed by drops which absorb a measurable fraction of the incoming light. The characteristics of techniques that comply with these requirements are specified. Guidelines have been defined for the detection of outliers, i.e. drops whose diameters or velocities strongly deviate from mean or characteristic values of the overall spray.
