RESUMO

The problem of flow of a viscous incompressible gas with dust particles across an isothermal cylinder is discussed. The dust particles are assumed to be uniformly distributed throughout the gas. The equations of motion are simplified by writing the equations in dimensionless form and then solved numerically to describe the flow for different values of the physical parameters of interest. These parameters are the particle concentration parameter (R), the temperature relaxation time parameter (A) and the particle mass parameter (G). Many results are obtained and a representative set is displayed in graphs and tables. It is found that a distinct decrease in the velocity function is observed with an increase in the particle concentration parameter and increasing particle mass parameter induces a reduction in velocity. Furthermore, comparisons with previously published work are performed and the results are found to be in excellent agreement.
