Analysis of a smart clutch with cooling flow using two-dimensional bingham plastic analysis and computational fluid dynamics

Abstract

Two-dimensional (orthogonal) steady isothermal flows of a Bingham plastic between two plates, one moving and the other stationary, are discussed. This is done principally to examine and quantify the concept of cooling a smart clutch by throughflow. The fluid is modelled conventionally as an ideal Bingham plastic to verify the subsequent use of a computational fluid dynamics (CFD) package for similar flows in more complex situations but with a futuristic view to including heat transfer, electrical conductance, thermal and shear rate effects on fluid properties, and unsteady motion. The CFD (Fluent) package incorporates a user-defined subroutine facility which allows non-Newtonian constitutive models to be incorporated. Both radial and concentric geometries are considered. The two approaches (conventional analysis and CFD) are seen to complement one another.

A review on multi-physics numerical modelling in different applications of magnetorheological fluids

“…The two-way coupled solutions are often to be performed by COMSOL/Multiphysics in which the AD/DC module is used for magnetic field simulation, whereas the fluid flow and heat transfer modules are used for fluid flow solution, as shown by Bompos and Nikolakopoulos (2011), Case et al (2013, 2014), Guo and Xie (2019), Li et al (2019b), Omidbeygi and Hashemabadi (2013), Wang et al (2017) and Zheng et al (2014, 2015, 2017). The non-coupled solutions are found where the magnetic field solution was not investigated, as by Bullough et al (2008), Cantelli (2009), Ellam et al (2006), Gedik et al (2012), Gołdasz et al (2018), Gstöttenbauer et al (2008), Li et al (2019a), Llorente and Pascau (2019), Manjeet and Sujatha (2019), Sahu and Sharma (2019) and Taibi and Messelmi (2017), or was implemented by analytical solutions, as shown in Chooi and Oyadiji (2008) and Singh et al (2014).…”

“…Ellam et al (2006) investigated the Couette flow of MR fluids between parallel plates and in concentric annuli. They developed an analytical model for the flow in parallel plates, and another steady-state, incompressible and isothermal CFD model for the flow in concentric annuli using ANSYS/Fluent.…”

“…The performances of these applications are found to improve significantly due to the rapid, reversible and controllable characteristics of MR fluids (Wang and Liao, 2011). Examples of these applications are journal bearings (Bompos and Nikolakopoulos, 2011), hydraulic valves (Bullough et al, 2008; Nguyen et al, 2008), micro-pumps (Liang et al, 2018), smart clutches (Ellam et al, 2006; Zhang et al, 2019), rotary MR dampers (Deng et al, 2019; Wang et al, 2019), robotics (Hartzell et al, 2019; Hwang et al, 2019), energy harvesters (Deng and Dapino, 2015; O’Donoghue et al, 2016), rheometers (Allebrandi et al, 2020), human prosthesis (El Wahed and Wang, 2019), engines mounts (Do and Choi, 2015), and hybrid body armours (Son and Fahrenthold, 2012). So far, there have been fewer studies on the employment of MR fluids in these applications compared to research efforts on linear MR dampers (Galindo-Rosales, 2016).…”

“…However, the main flow is categorised under the flow mode (Khan et al, 2014). Examples of devices that employ shear mode are rotary dampers (brakes), clutches and parallel-plate rheometers (Chan et al, 2011; Du et al, 2014; Ellam et al, 2006; Gurubasavaraju et al, 2018a; Jang et al, 2011; Khan et al, 2014; Liu et al, 2016).…”

Model of an electro-rheological shock absorber and coupled problem for partial and ordinary differential equations with variable unknown domain

“…Various problems on dynamics of electrorheological clutches and valves were formulated and studied in [6], [7], [32]- [35]. However, to the best of our knowledge, the problem of the electrorheological shock absorber has not been formulated and studied.…”
