Abstract
Starting from a historic perspective, we discuss the use of second sound in experimental investigations of quantized vorticity and quantum turbulence in the two-fluid temperature regime of superfluid $$^4$$ He. Starting with the theoretical prediction of second sound by Tisza and Landau and its experimental discovery by Peshkov, we briefly review the pioneering experiments of Hall, Vinen and others that have contributed in an essential way to our current understanding of quantum turbulence in superfluid $$^4$$ He, with an emphasis on relevant research performed over the last two decades in our laboratory in Prague. We then propose further dedicated experiments where second sound can be used both as a generator and detector of quantum turbulence.
