“…Singleton [8] was the first to study the boundary layer analysis for dusty fluid and later on several attempts were made to conclude the physical insight of such two-phase flows (see Ref. [9]- [17]) under different physical circumstances. Very recently, numerical solutions for the influence of thermal radiation on natural convection flow of dusty fluid past a vertical wavy frustum of a cone are presented by Siddiqa et al [18].…”

This article is concerned with the class of solutions of gas boundary layer containing uniform, spherical solid particles over the surface of rotating axi-symmetric roundnosed body. By using the method of transformed coordinates, the boundary-layer equations for two-phase flow are mapped into a regular and stationary computational domain and then solved numerically by using implicit finite difference method. In this study, a rotating hemisphere is used as a particular example to elucidate the heat transfer mechanism near the surfaces of round nosed bodies. We will also investigate whether the presence of dust particles in carrier fluid disturb the flow characteristics associated with rotating hemisphere or not. A comprehensive parametric analysis is presented to show the influence of the particle loading, the buoyancy ratio parameter and the surface of rotating hemisphere on the numerical findings. In the absence of dust particles, the results are graphically compared with existing data in the open literature and an excellent agreement has been found. It is noted that, the concentration of dust particles parameter, D ρ , strongly influence the heat transport rate near the leading edge.

“…Patrulescu et al [15] studied mixed convection nanofluid flow over a vertical frustum of a cone and shown that an increase in the mixed convection parameter decreases the heat transfer characteristics. Siddiqa et al [16] discussed two-phase dusty fluid flow over a vertical frustum of a cone and concluded that the rate of heat transfer rate significantly increases by the inclusion of nanoparticles. Amanulla et al [17] examined Casson nanofluid past a truncated cone texture and analyzed that the buoyancy ratio parameter increases the fluid flow.…”

In this article, the impact of water-based hybrid nanofluid on heat transfer characteristics along the wavy frustum of the cone is examined. We considered hybrid nanofluid containing and nanoparticles. Non-similar form of the constitutive equations is obtained by using an appropriate set of transformations and results are achieved by employing transformed into compact non-similar form and are solved by the famous numerically implicit finite difference scheme known as Keller-box technique. The influence of the hybrid nanoparticles? volume fraction, frustum of cone half-angle and the wavy texture parameters on the Nusselt number and skin friction are scrutinized and comparison is made between the wavy frustum of the cone and flat frustum of the cone through numerical data. It is observed that the rise in the truncated cone half-angle leads to an increase in skin friction and Nusselt number. Titania - water nanofluid has lower heat transfer rates as compared to copper-titania hybrid nanofluid. The increasing of the truncated cone half-angle enhances the heat transfer rates. Generally, the results established from this analysis can be used as a benchmark for improving the natural convection heat transfer performance along the frustum of cone wavy texture.

“…One of the important aspects of this problem for fluid phase is that it can treated as Newtonian and non-Newtonian fluids which stimulates continuing interest within this area of research. Theoretical works covering on suspension of dust particles in Newtonian fluid with dissimilar circumstances have been reported by several researchers, as documented in [1][2][3][4][5]. A recent study reported by Kumar et al, [6] caters the problem on dusty fluid flow under the effect of mixed convection over a stretching cylinder by taking into account the nanoparticles.…”

Numerical investigation of the boundary layer flow of Williamson fluid with the presence of dust particles over a stretching sheet is carried out by taking into account the variable viscosity effect and Newtonian heating boundary condition. The genuinely two-phase flow model which has been proved to be compatible to present the mutual relationship between non-Newtonian fluid and solid particles is considered in this present study. To be precise, the governing equations are initially transformed into ordinary differential equations through formulation process before proceeding further with the numerical computation by using Keller-box method. The resulting equations are then programmed in Matlab software. The obtained numerical results are validated with existing study found in open literature and a good agreement is achieved. The influence of pertinent parameters on velocity and temperature profiles, skin friction coefficient together with Nusselt number is presented in graphical and tabular forms. Results revealed that the increasing Williamson parameter decreases the fluid velocity of both fluid and dust phases. It is expected that the present numerical results could conceivably help in predicting the boundary layer problem arising in two-phase flow in the future.
