title = "A novel steady-state technique for measuring the heat extracted by secondary cooling sprays",
abstract = "This paper presents a new technique for measuring the steady-state heat flux extracted locally by water sprays or air-mists impinging upon the surface of a hot metallic body. The technique is based on balancing the induction heating of a metallic sample with the heat removed by the boiling of spray droplets impinging on its exposed surface. Measurement of the RMS current flowing through the induction coil for maintaining a desired sample temperature, together with the solution of a two-dimensional axisymmetric computational model of the electromagnetic and heat conduction equations, enable estimation of the heat extracted by the cooling spray. Heat fluxes are reported for spray cooling of a Pt sample at temperatures spanning from 200-1200°C, using air-mist nozzles and operating conditions relevant to continuous casting of thin steel slabs. The results demonstrate the flexibility of the technique for investigating different aspects of spray cooling.",
