Joule–Thomson expansion of regular Bardeen AdS black hole surrounded by static anisotropic matter field

In the present paper, we investigate required anisotropy of an exact regular Bardeen black hole characterized by its mass $M$, nonlinear parameter $g$, quintessence field $a$ in anti-de sitter spacetime with a static matter field. We also show that relative pressure anisotropy, equation state and depends on radial coordinate, reflecting for background. Next, analyze Joule-Thompson ($JT$) expansion spacetime. Treating cosmological constant as thermodynamic $P$ conjugate quantity volume $V$ derive connecting Hawking temperature various parameters. study $JT$ AdS holes background through analysis inversion isenthalpic curves. coefficient $\mu$, use them to plot discuss effect $\omega_q$ temperature, especially case $\omega_q=-1$ $\omega_q=-\frac{1}{3}$. Our shows dark energy affects point $(T_i,P_i)$ .
