  In this paper, we study Joule-Thomson expansion for Kerr-AdS black holes in
the extended phase space. Joule-Thomson expansion formula of Kerr-AdS black
holes is derived. We investigate both isenthalpic and numerical inversion
curves in the T-P plane and demonstrate the cooling-heating regions for
Kerr-AdS black holes. We also calculate the ratio between minimum inversion and
critical temperatures for Kerr-AdS black holes.
