Autocatalytic reaction mechanism of nitric acid and formic acid mixtures based on thermal and in situ Raman spectroscopic analyses
Journal of Thermal Analysis and Calorimetry - Tập 144 - Trang 553-562 - 2020
The oxidation of organic compounds with nitric acid has the potential to undergo a runaway hazardous reaction and explosion after the thermal–neutral induction period. The purpose of this study is to obtain a better understanding of the oxidation reaction mechanism to clarify the specific conditions under which the exothermic reaction occurs. In this study, the oxidation reactions of formic acid w...... hiện toàn bộ
A novel method for quantitative phase determination of cristobalite in ceramic cores using differential scanning calorimeter
Journal of Thermal Analysis and Calorimetry - Tập 119 Số 1 - Trang 191-195 - 2015
Sensitivity of AHU power consumption to PCM implementation in the wall-considering the solar radiation
Journal of Thermal Analysis and Calorimetry - Tập 143 - Trang 2789-2800 - 2020
This study examined the efficacy of PCM implementation in the wall on the thermal performance of the air handling unit (AHU). For this, a PCM layer (2 cm) was incorporated into the base wall with a thickness of 23 cm to investigate the PCM presence efficacy on heat transfer reduction. Considering the solar radiation effects on the building envelope, the sensitivity of the heat transfer reduction t...... hiện toàn bộ
Comparative study between step and sinusoidal temperature profiles during natural convection inside a square enclosure heated from bottom
Journal of Thermal Analysis and Calorimetry - Tập 148 - Trang 2815-2830 - 2023
The core goal of the current theoretical exertion is to explore the impacts of step and sinusoidal bottom heating patterns on the buoyancy-driven flow and their heat flow aspects that are triggered by the temperature gradient inside the cavity which is commonly essential for many engineering applications like solar cells, food processing unit, materials processing unit, nuclear reactor core, etc. ...... hiện toàn bộ
DMA analysis, thermal study and morphology of polymethylsilsesquioxane nanoparticles-reinforced HDPE nanocomposite
Journal of Thermal Analysis and Calorimetry - Tập 139 - Trang 789-797 - 2019
High-density polyethylene (HDPE) nanocomposites were prepared by a melting-compounding process with a polymethylsilsesquioxane (PMSQ) as nanofiller. In this process, the PMSQ nanoparticles were swollen in an organic solvent using a Ultra-Turrax system and sonication and blended with molten HDPE using a twin-screw extruder. This was followed by solvent removal. Nanocomposites with different PMSQ ma...... hiện toàn bộ
A study on the effect of magnetic field and the sinusoidal boundary condition on free convective heat transfer of non-Newtonian power-law fluid in a square enclosure with two constant-temperature obstacles using lattice Boltzmann method
Journal of Thermal Analysis and Calorimetry - Tập 144 - Trang 2557-2573 - 2020
In this paper, the flow pattern and thermal characteristics of free convection of a Newtonian magnetohydrodynamic fluid flow inside a square enclosure are compared against two different non-Newtonian power-law (PL) fluids. The enclosure with horizontal insulated walls has two constant-temperature obstacles, while two sidewalls are differentially heated with sinusoidal pattern. Boussinesq approxima...... hiện toàn bộ

Numerical study of laminar pulsed impinging jet on the metallic foam blocks using the local thermal non-equilibrium model
Journal of Thermal Analysis and Calorimetry - Tập 141 - Trang 1859-1874 - 2020
In this study, thermal performance of an impingement jet with the presence of porous block is numerically investigated. The study is comprised of two main parts. At first, a parametric study is conducted on the steady impingement jet with porous block. Later, the effect of porous block is assessed on the pulsative impingement jet. The effect of different pulsation frequencies and amplitudes is ana...... hiện toàn bộ
Effect of two imidazole ionic liquids on the thermal stability of cumene hydroperoxide
Journal of Thermal Analysis and Calorimetry - Tập 148 - Trang 5051-5062 - 2022
Organic peroxides combined with ionic liquids had a high application value in the desulfurization process. However, thermal stability between organic peroxides and ionic liquids displayed a significant difference. Moreover, it was of great significance to investigate the thermal hazard of organic peroxides due to the influence of ionic liquids. In this study, a common organic peroxide cumene hydro...... hiện toàn bộ
