摘要：

In this paper, the P - V criticality and Joule-Thomson Expansion of Hayward-AdS black holes in 4D Einstein-Gauss-Bonnet gravity are studied in the extended phase space. We find the black hole always exhibits a phase transition similar to that of the Van der Waals system for any arbitrary positive parameters alpha and g. We also study the dependence of alpha and g on the inversion curves and plot the inversion and isenthalpic curves in the T - P plane, which can determine the cooling-heating regions.
