Magnetic fluid‐based squeeze film behavior between transversely rough curved annular plates: a comparative study

Purpose – This paper aims to improve upon the performance of magnetic fluid‐based squeeze film between transversely rough curved annular plates by embarking on a comparative study of the geometrical structure of the curved annular plates.Design/methodology/approach – The objectives are met by mathematically modeling a magnetic fluid‐based squeeze film between transversely rough curved annular plates. The standard method is to solve the associated Reynolds' equation with appropriate boundary conditions by describing the random roughness through a stochastic random variable with non‐zero mean, variance and skewness. Results for bearing performance characteristics such as pressure distribution and load‐carrying capacity are numerically computed. In order to analyze the quantitative effect of the roughness, different geometrical structures of surfaces have been considered and the results are compared.Findings – Certainly, the performance of the bearing with the magnetic fluid lubricant is comparatively better...
