“…In Figure 7, the line represents the distribution of temperature along the fin, and the fin is at the base of domain red colour represent higher temperature and its equal 300C 0 . Along the fins, there are some dark colours represent the temperature variation on the fin [30][31][32][33][34]. There is a variation of the temperature due to heat dispersion along the fin, and the blue colour in the line represents the lowest temperature, equal to 287.581C 0 in this case.…”

“…The indication of the results that the pin fins heat sink with multiple circular stenosis have lesser pressure drop and high heat transition, difference to regular pin heat sink. This study aims to show the fin shape effect on behavior of heat transfer, the fins are used in a variety of engineering applications such as mechanical and electronic devices [29][30][31][32]. Two shapes of straight aluminum fins have been used, cylindrical and star shape, and maintains the base temperature at 300C.…”

The convection heat transfers on a surface exposed to the fluid may be enhanced by attaching to the surface, known as the fins. To keep the system stable, heat transmission via solids, boundaries, or walls must be continuously dissipated to the environment or surroundings. A large quantity of heat must be dissipated from a small space in many engineering applications. A fin can boost the surface area’s effectiveness; hence, maximize convectional heat. Two shapes of straight aluminum fins have been used, cylindrical and star shape. The result shows that the star fins are appealing due to the same diameter and length; it has a lot more heat transfer than a cylindrical fin. In electronic devices, cylindrical and star fins are provided on the surface of the processor device. The result is done by SolidWorks simulation with 300 ºC on the surface as well as cylindrical and star fin. Input parameters like thermal conductivity, heat transfer coefficient, as well as fin’s density and dimensions are measured. The temperature distribution, heat flow, as well as heat flux all resembles output parameters.

“…The effectiveness of heat and mass transfer control via implementing modified laws in cooling procedures was evaluated by Lyu et al (2022). Heat transfer in an annulus by varying the shape and number of fins was explored by Madhavadas et al (2021). They deduced that the efficiency of the heat exchanger is conclusively dependent on the orientation of fins.…”

Analysis of free and forced convections in the flow of radiative viscous fluid with oxytactic microorganisms

The prime intend behind the current effort is to explicate flow attributes of magnetically influenced Newtonian fluids toward a stretchable sheet under the novel physical impact of oxytactic microorganisms in a comparative manner for free and forced convections. In addition, modified Fourier and Fick’s laws are implemented to examine the change in temperature and concentration distributions in a more realistic manner by accounting thermal and mass relaxation parameters in the flow. The obtained PDEs are reduced into the non-linear ODEs by employing similarity variables. Due to the complexity of parametrically based differential equations, a numerical scheme based on a finite-difference approach is implemented via the MATLAB built-in routine known as BVP4C. Flow-controlling parameter effects on associated distributions are evaluated through graphs and tables. Subsequently, the influence of flow-controlling parameters on associated distributions is revealed through pictures in a comparative manner for different convection regimes. Additionally, the quantities such as heat and mass fluxes along with the density of motile microorganisms are also illustrated. From the thorough analysis of the current investigation, it is inferred that velocity distribution enhances for free and forced convections, whereas the temperature of the fluid diminishes against the mentioned convective regimes. It is manifested that the Nusselt number is more in the situation of free convection instead of the forced convection situation. The magnitude of the skin friction factor is more in case of free convection as compared to the forced convection regime. It is also reported that by uplifting the magnitudes of concentration and thermal relaxation parameters, depreciation in associated heat and mass transfer rate arises. In addition, it is also reported that with the increment in the magnetic field, buoyancy ratio, bioconvection parameters, and Rayleigh number skin friction accelerate, while the behavior is quite opposite in case of stretching the ratio parameter.

“…[1][2][3][4][5] The FDM printers work by deposition of the filament layer by layer. The 3d printer hotends consist of five major components which are, Heat sink, Heat break, Nozzle, Heater block and Heating shaft which are used in the finite element analysis [6][7][8][9][10] The Heat sink plays an important role in dissipating heat from the hotend to the environment and also helps in maintaining a perfect temperature distribution across the heat break for the filament to melt. The Heating shaft is usually made of stainless steel and it acts as a heat source for the hotend, to melt the filament for deposition.…”

Nowadays, the desktop 3D printers are common in computer aided manufacturing and widely used in multiple applications across homes, offices, and in several business sectors, etc. A wide variety of filaments like PLA, ABS, PETG, TPU, etc. are now being used in Fused Deposition Modeling (FDM). These filaments require different temperatures to print. FDM is a process in which a material in its filament form is melted and deposited layer by layer to form the required object. The hot end of a printer plays a crucial role in the melting of these filaments for printing. It is a major component of a 3D printer, where the filament is brought to a semi-solid state, to extrude and deposit the filament in layers. In this research study, the hot end of "Ender 3" and "CR-10S Pro" are modeled using Computer Aided Designing software, and thermal analysis using Finite Element Analysis, is carried out by applying the maximum printing temperature of PLA for the two printer hot ends. To optimize the problem of wide temperature gradient which often results in clogs and jams across the hot end, the design of heat sink is modified to maximize heat dissipation. Alongside, the simulation result is also compared with manual experimental readings.
