A thermohydraulic characterization of a reciprocating room temperature active magnetic regenerator was numerically carried out in this chapter, using gadolinium particles as a magnetocaloric material and water as a heat transfer fluid. For varying water inlet velocities of 0.06, 0.08, 0.1, and 0.12 m.s -1, a two-dimensional transient flow...

The impact of changing dynamic viscosity in combination with viscous dissipation on convective heat transfer in a fluid-filled rectangular cavity is studied using numerical simulations. At the top of the chamber, a heated horizontal plate is kept at temperature Tw and moves at a constant velocity Uw. Additionally, cold...

Heat transfer is a common occurrence in manufacturing and other aspects of life, therefore specific applications of heat transfer are not difficult to come by. When two systems have a temperature difference, heat is a form of energy in transmission that moves from one to the other without transferring...

The steady-state heat transfer study in a 4-pass fire-tube boiler is the subject of this paper. The heat transmission between the combustion gases and the boiler tube walls has been studied using a computer software. The energy balance was constructed on these surfaces, taking into account heat movement by...

Radiative heating is a viable alternative to steam or lye, which are both expensive and polluting ways for peeling tomatoes. In order to realise short-time operations using only a tiny layer underneath the tomato surface, suitable energy densities are necessary. The goal of this study is to forecast the...

We investigated blood flow through an indented artery in this article, assuming blood to be Jeffrey fluid. The impact of heat transfer on the flow profile of Jeffrey fluid in an indented artery is investigated in this analysis. The governing equations are also converted into coupled Bessel differential equations...

This paper considers an exothermic chemical reaction in a stockpile of reactive material with temperature-dependent thermal conductivity. The research is focused on a spherical domain in which carbon-containing material interacts spontaneously with trapped oxygen. The combustion process generates a complex, nonlinear process, and the energy equation that governs the...

Artificial roughnesses in the form of ribs are an advantageous technique to improve solar air heaters’ warmth quality. This research work introduces new roughness utilized in a roughened channel and assesses the effective efficiency for a gap of inclined discrete rib with staggered link geometry. A good system for...

The nonlinear problem of the flow of Newtonian fluid in a microchannel between two parallel plates was discussed in this paper with the effects of velocity slip, viscous dissipation, and wall temperature leap. Both the Navier-Stokes equation and the energy equation model this problem with two thermal boundary conditions...

In this study the performance of one numerical turbulence model, k- ε is accessed. In predicting heat transfer due to natural convection inside an air-filled square cavity. Turbulent natural convection in an enclosure plays an important role in the field of heat transfer and buildings environment. Natural turbulent convection...
