Analytical Solutions for Tomato Peeling withCombined Heat Flux and Convective Boundary Conditions

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 temperature field in rotating tomatoes that…

MHD Oscillatory Flow of Jeffrey Fluid in an Indented Artery with Heat Source

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 and solved analytically. The effects of…

Recent Study on Heat Transfer Analysis for a Sphere of Combustible Material of Variable Thermal Conductivity

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 problem is numerically solved using the…

A Report on the Analytic Approximations for the Flows and Heat Transfer in Microchannels between Two Parallel Plates

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 related to the two cases: the…
