Analysis of periodic heat transfer through extended surfaces

Abstract

This article is concerned with the review of periodic heat transfer through extended surfaces known as fins. In this review, we bring out the detail study of heat transfer of periodic type variation through extended surfaces. Heat transfer which has been remained a warm area of research under various conditions for the researchers in last many decades. In the current analysis, an attempt is appointed to study, analyze and summarize the result of the periodic heat transfer and flow in various fins. Further, we are carried out the analysis for the periodic heat transfers through various kind of extended surface also called fins in the presence of periodic base and ambient temperature. The performance of the extended surface is expressed in terms of the fin effectiveness and its efficiency. The heat transfer process is regulated by three experimentally determined dimensionless parameters such as the frequency parameter w, the convectional fins parameter N, and the amplitude parameter A. Further the fins performance and efficiency are demonstrated through several examples.

Deterministic Model and Analysis of Fuel Subsidy in Nigeria Commodity Market Dynamics

“…Mathematics model has been exploited in unraveling the dynamics of biological phenomena including coronavirus see [28,29], cancers [30,31,32], Measles [33] among others. Also, the uses of Mathematics modeling in studying the periodic heat transfer as in [34], fractional electric circuits as in [35]. Recently, Mathematical models have also been used in studying the impact of subsidy dynamics in the Nigerian economy: Odior [36] assess the likelihood of 142.8 percent (₦200 Per liter) subsidy removal on both the Nigerian welfare and macroeconomic using a Structuralist Computable General-Equilibrium (CGE) model to simulate the effect of fuel subsidy removal between 2015 -2020.…”
