This work proposes a vibrating mesh screen as an alternative to the static currently used in conventional flooded-bed dust scrubbers for removing airborne coal mine continuous mining environment. Fundamental assessments suggest that may improve collection efficiency of scrubber systems and mitigate clogging issues associated with design. To evaluate this hypothesis, computational fluid dynamics (CFD) simulations were carried out assess effects vibration conditions (i.e., frequency amplitude)...

In this paper, an analytical investigation of two-dimensional conventional Burnett equations has been undertaken for gaseous flow through a long microchannel. The solution is obtained by using perturbation analysis around the classical Navier–Stokes with appropriate boundary conditions. expansion employed smallness parameter $\unicode[STIX]{x1D716}$ , taken as ratio height to length pressure solving cross-stream momentum equation while velocity distribution from streamwise equation....

This work builds upon recent exploiting the notion of structured singular values to capture nonlinear interactions in analysis wall-bounded shear flows. In this context, uncertainty can be interpreted terms flow structures most likely amplified (the optimal). Here we further analyze these perturbations through a problem reformulation that decomposes into three components associated with streamwise, wall-normal and spanwise velocity correlations. We then demonstrate structural features...

This paper presents an analytical solution of the Burnett equations for gaseous flow in a long microchannel. A non-dimensional analysis is first undertaken to reduce governing into somewhat simplified differential equations, which are solved obtain pressure and velocity fields. The exact has been obtained by solving cross-stream momentum equation, while from streamwise equation. required boundary conditions direct simulation Monte Carlo (DSMC) method. compared with available DSMC...
