The study introduces a novel approach to squeeze film behavior by combining Micropolar fluid, its piezo-viscous dependency, and MHD effects on wide parallel rectangular plates. The Reynolds equation is developed analyticaly by utilising the principles of hydromagnetic flow, Eringen’s microcontinuum theory, the micropolar fluid model and the influence of variable viscosity.The current study seeks to maximize the bearing performance by scrutinizing the pressure, load carrying capacity, and squeezing time. The influence of Hartmann number M, coupling number N, fluid gap interacting number L, and Piezo-Viscous Dependency parameter G are numerically calculated and depicted graphically. Notably, the pressure, the load carrying capability, and squeezing time are enhanced by the presence of the micropolar fluid and the magnetic field compared to their Newtonian and non-magnetic counterparts. Additionally, the piezo-viscous dependency, characterized by the viscosity variation factor, also increases the pressure, load and squeezing time. The study highlights the potential of utilizing couple stress fluid, viscosity variation, and MHD as a means to improve load carrying capability and extend the operational life of squeeze film bearings in various engineering applications. The Reynolds equation is derived by applying theory of hydromagnetic flow and Eringen’s micro continuum theory along with micro polar fluid model.

Volatile organic compounds (VOCs) are chemical substances that evaporate quickly, releasing harmful fumes into the atmosphere. Among the various VOCs, toluene and n-propanol are particularly interesting due to their widespread occurrence and considerable industrial impact. This study uses a bio-reactor with microbial biofilm formation to present the bio-degradation of a composition of toluene (methylbenzol) and n-propanol (1-propanol). It predicts the coupled inhibition effect of n-propanol on the toluene removal efficiency. The bio-filtration process is modelled as a dynamical system using a set of deterministic nonlinear partial differential equations. The differential equation with its appropriate conditions describes the bio-filtration processes occurring in two distinct phases: the biofilm phase and the gaseous phase. The differential equation is solved using the Chebyshev pseudospectral method and the local linearization method to understand the physical dynamics of the mathematical model. The effectiveness of the spectral-based method was evaluated by comparing its accuracy to known results in the limiting cases of the current dynamical model. A parametric and partial rank correlation coefficient (PRCC) analysis of the dimensionless parameters is conducted. It was found that toluene removal is enhanced by the additional desorption rate constant, ζ2. Increasing the air-biofilm coefficient for n-propanol supports the removal of n-propanol but not that of toluene. The findings of this study contribute to improvements in bio-degradation modelling and enhance our understanding of volatile organic compounds.
