Thermal stability with emission energy and Joule–Thomson expansion of regular BTZ-like black hole

Abstract We investigate the thermodynamic properties and Joule–Thomson expansion for conical or BTZ-like black holes. To analyze thermal stability, we discuss temperature stability relative to horizon radius different values of model parameters $$\beta _0$$ β 0 $$\alpha _2$$ α 2 . Moreover, thermodynamical geometries like Ruppeiner, Weinhold Hendi Panahiyah Eslam Momennia formulation calculate respective scalar curvatures Interestingly, holes have no singularity in some cases, i.e., completely regular. obtain inversion temperatures curves similarities differences between van der Waals charged fluids. this expansion, use a hole. Further, establish position point versus mass $$\mu $$ μ , such The coefficient at disappears. A crucial trait upon which relied inspect sign quantity get cooling-heating areas. also energy emission depending frequency $$\omega ω
