“…However, his results show close agreement with Massey and Clayton [9]. A few notable studies related to non‐Newtonian fluids were found in [16–25], heat transfer along with nanofluids [26–36], and stretching surfaces [37, 38].…”

The underlying intention of the present work is to elaborate the boundary layer flow of Carreau fluid over a non‐linear stretching curved surface. Firstly, we derived the equation of motion for a two‐dimensional curved surface using the Carreau constitutive relation. Employing the well‐known approximations of the boundary layer theory (order of magnitude analysis), the terms of higher and next order have been neglected. We developed an appropriate similarity transformation that reduced the considered partial differential equation into an ordinary differential equation (self‐similar formulation). The MATLAB built‐in function usually known as bvp5c is utilized to get the numerical solution of the considered problem. The impact of the power‐law index (n), Weissenberg number and curvature parameter (k) on velocity profile and skin friction are analyzed through several graphs and tables. The obtained results are also verified by employing the shooting method through Maple software. The results reveal that both boundary layer thickness and velocity profile increase by enlarging the dimensionless curvature parameter of the curved surface.

“…Many studies on the analysis of heat transfer from various geometrical shapes with different fluid models and different flow assumptions have recently been discovered (see, for instance [29][30][31][32][33]), which inspire us to continue filling in the gaps. In the above-cited literature, only [16] and [28] cover the studies in which the bodies of revolution having a variable radius have been considered.…”

Heat transfer analysis in a retarded laminar boundary layer over bodies of revolution with a variable radius subject to retarded surface temperature is presented. This study focuses to develop numerical data for local Nusselt number Nu_x under the influence of retarded free stream velocity and decreasing surface temperature along with body contour and surface transverse curvature. With the use of such retarded velocities and body contour the similarity of flow phenomenon does not sustain, and the problem becomes non-similar in nature which has been solved using an efficient numerical scheme, commonly known as Keller-Box. The effects of pertinent parameters such as exponent of free stream velocity m, exponent of surface temperature q, body contour n, and surface transverse curvature k on temperature profile, rate of heat transfer at the surface, and energy thickness of thermal boundary layer are presented through various graphs and tables. The rate of heat transfer and the energy thickness of the thermal boundary layer are observed to decrease with increasing levels of retardation. Furthermore, the rate of heat transfer decreases as the body contour parameter increases, whereas the surface transverse curvature parameter exhibits the opposite trend.

“…Numerical simulations such as computer-aided engineering (CAE) [9][10][11][12] and computational fluid dynamics (CFD) [13][14][15] are used instead of experiments, greatly saving costs of time and money. Scholars have used CFD [16][17][18][19][20][21] and CAE [22][23][24][25] methods in the study of nanofluids [26,27], bionic engineering [28,29], engineering architecture [30], and other fields. Computer-aided simulations enable the observation of many details that cannot be captured by experiments, allowing for more in-depth studies.…”

Torquigener albomaculosus, also known as the white-spotted pufferfish, is known for creating circular nests in the underwater sand as part of the mating ritual. The nests are built by the males to attract females through the nest's impressive design and related ability to gather fine sand particles. As the fluid-dynamic processes associated with these unique nests are still almost completely unknown, in the present study, an analysis has been conducted to investigate how the geometric parameters related to the nest design influence the fluid velocity in its center. For this reason, a geometric model of the nest consisting of 24 channels, where each unit channel can be described by three strips of broken lines, has been introduced, and a multivariate analysis has been implemented to determine the relative weight of each considered parameter. In particular, the "optimal" combination of parameters has been obtained by means of an orthogonal design approach. We show that these bio-nest structures also display a potential for significant application in marine litter collection, or for use as a buffer against the waves in offshore areas.
