The aim of this research is to study the effects of thermal radiation and chemical reaction on hydromagnetic fluid flow in a cylindrical collapsible tube with an obstacle. The fluid flow is governed by continuity, momentum, energy, and concentration equations. Similarity transformation has been used to convert the obtained PDEs into ODEs. The collocation method has been used to numerically solve the ODEs. The method has been implemented in MATLAB using the bvp4c inbuilt function. The effects of the nondimensional parameters on velocity, temperature, and concentration have been presented graphically. Additionally, the skin-friction coefficient, the Nusselt number, and the Sherwood number have been discussed and are presented in a tabular form. The findings demonstrated that increasing the Reynolds number causes a rise in the fluid temperature and velocity. The fluid velocity decreases as the Hartmann number and the weight of the obstacle increase but increases with increasing Grashof numbers. The temperature of the fluid increases as the radiation parameter, or Eckert number, increases, but decreases as the Prandtl number increases. As the Soret number rises, so do the fluid’s temperature and concentration distribution. With an increase in the unsteadiness parameter, the fluid velocity and the concentration distribution decrease, whereas the opposite is seen in temperature. As the Schmidt number, the concentration Grashof number, and the chemical reaction parameter increase, the fluid’s concentration decreases. There is an increase in skin-friction coefficient with increasing Prandtl number, Eckert number, Soret number, thermal Grashof number, concentration Grashof number, thermal radiation parameter, Hartmann number, and unsteadiness parameter, while a decrease is observed with increasing Reynolds number. The Nusselt number increases with an increase in the Prandtl number, Eckert number, thermal radiation parameter, Hartmann number, and unsteadiness parameter. A slight decrease in the Nusselt number has been observed with increasing thermal Grashof number. The Sherwood number decreases with increasing Prandtl number, chemical reaction parameter, and thermal radiation parameter but increases with increasing Schmidt number, Eckert number, and Soret number. The research has the potential for a wide range of applications including but not limited to the medical field and other physical sciences.

The physiological systems and biological applications that have arisen during the past 15 years depend heavily on the microscale and nanoscale fluxes. Microchannels have been utilized to develop new diagnostic assays, examine cell adhesion and molecular transport, and replicate the fluid flow microenvironment of the circulatory system. The various uses of MHD boundary flow in engineering and technology are extensive, ranging from MHD power generators and the polymer industry to MHD flow meters and pumps and the spinning of filaments. In this investigation, the (Magnetohydrodynamic) MHD flow of Prandtl nanofluid is investigated along with mixed convection, energy activation, microorganism, and chemical reaction. The flow model is considered through partial differential equations in dimensionless form which is then integrated numerically via considering the Bvp4c technique. The outcome is numerous emerging physical parameters over velocity profile, temperature, mass concentration, and microorganism with the separate pertinent quantities such as the Prandtl fluid parameter, elastic fluid parameter, magnetic field, mixed convection parameter, activation energy, chemical reaction, Brownian motion, thermophoretic force, Prandtl number, and Schmidt number. The friction factor, rate of heat transfer and Sherwood number, and density of microbes are revealed numerically and graphically. The outcomes indicate that the Prandtl fluid parameter and elastic fluid parameter tend to enhance the velocity profile. It is also noted that the Prandtl fluid parameter depreciates the thermal rate with the addition of the concentration profile while the opposite trend is recorded for activation energy. Obtained numerical outcomes are correspondingly compared with the current statistics in limiting cases and a close match is obtained.

“…The results also show that oscillatory behaviour and complex patterns are possible in bioconvection, which opens up new directions for study and application in fluid dynamics and related fields. Recently [29], its objective is to reveal how gyrotactic microorganisms affect heat and mass transfer in polymerized Cross fluid flow in a time-dependent MHD flow model. A constraining condition is applied to non-linear thermal radiation, viscous dissipation, and Soret and Dufour effects.…”

This theoretical study illustrates the effect of an inclined stretching sheet with bio-mixed convection, aligned magnetohydrodynamics (MHD), porous medium, Joule heating, viscous dissipation, the Buongiorno nanofluid model, and chemical reaction effects. Stefan blowing (SB) and partial slips, as well as our presumptions and laws, like the conservation of mass, momentum, and energy, must all be taken into consideration when solving our partial differential equations (PDEs). Similarity transformations are used in the context of a gyro-tactic motile microorganism flowing through an inclined stretched surface to produce ordinary differential equations (ODEs). The BVP4C method generates numerical results for different parameters through MATLAB programming. Additionally, a numerical and graphical exploration of the effects of numerous developing variables on the velocity, temperature, concentration, and density of motile bacteria is done. To verify the accuracy of the numerical model, the findings of the numerical research are compared to experimental data. Microbial distribution decreases with both negative and positive SB (suction and injection) attitudes, as indicated by the Peclet number and microbe movement coefficient. The mobility of microorganisms increases with higher values of the Lewis number, which governs their motility. The Lewis number and chemical reaction parameters affect the volume fraction transfer during the flow of the nano-Casson fluid in both the suction and injection cases of the SB effect, leading to increased concentration transfer.
