In the course of He II-He I phase transition studies, one phase of the investigations has been concerned with free convection in He I with the aim of simulating the heat transfer in rotating superconducting windings. A geometry similar to C-frame loops has been used in studies of free convection between the λ-curve and the transposed critical curve at pressures between 0.3 and 1.5 MPa. Related model calculations have been carried out for cellular convection. A comparison of the data obtained shows reasonable agreement with the model results.
