Using a logarithmic warp factor and working in the grand canonical ensemble, we analyze the temperature-horizon relation, entropy density, grand potential, pressure, energy density, and trace anomaly, demonstrating the emergence of a first-order phase transition at low chemical potentials, a critical end point, and a smooth crossover at higher chemical potentials. Thermodynamic response functions, including the heat capacity and charge susceptibility, exhibit finite jumps at the first-order transition, divergence at the critical end point, and broad maxima in the crossover region. These results collectively establish a consistent and QCD-like phase structure in this holographic framework. https://ijaa.du.ac.ir/article_2076.html This paper presents a time-dependent model for magnetized, advection-dominated accretion flows (ADAFs) that incorporates non-ideal effects, specifically resistivity and saturated thermal conduction. We apply a self-similar method to transform the full time-dependent magnetohydrodynamic (MHD) equations into a set of coupled ordinary differential equations, enabling us to investigate the evolving radial structure influenced by turbulent viscosity, magnetic diffusivity, and non-local energy transport. The resulting solutions confirm that the flow structure is inherently time-dependent. Numerical results demonstrate that increasing the efficiency of outward energy transport via saturated conduction weakens turbulence, reduces dissipation and temperature, increases density, and reduces the radial infall velocity while increasing the rotational velocity. In contrast, stronger magnetization leads to enhanced magnetic fields, lower temperatures, and faster radial inflow. We further show that the turbulence prescription parameter, which controls the pressure dependence of transport coefficients, significantly influences the balance between magnetic and thermal support. This framework offers a dynamic perspective on magnetized accretion flows, highlighting how non-ideal magnetic effects and conduction regulate the flow structure.
