This paper performs a theoretical analysis of suspended microchannel resonators (SMRs) containing one single or two parallel channels, modeled here as cantilevered micropipes conveying fluid and nanoparticle, and investigates the effects of flow velocity and nanoparticle’s instantaneous position on natural frequency, stability, and damping. For two-channel micropipes (TCMPs), the governing equation is derived using the Newtonian approach by essentially accounting for the flow-induced tensile for...

A nonlinear theoretical model for electrostatically actuated microcantilevers containing internal fluid flow is developed in the present study, which takes into account the geometric and electrostatic nonlinearities. A four-degree-of-freedom and eight-dimensional analytical modeling is presented for investigating the stability mechanism and nonlinear dynamic responses near and away from the instability boundaries of the fluid-loaded cantilevered microbeam system. Firstly, the reliability of the ...
