“…Then by substituting Equation (12) into Equation (10) and expanding the equation while terms of the same order of p are collected together, the resulting expression will appear in form of a polynomial in p. Moreover, by equating the coefficients of the polynomial in p to zero, we derive a set of differential equations and their corresponding boundary conditions as…”

“…a combination of two or more methods to investigate the thermal behaviour of fin under different operating conditions. Example of these methods include: Runge-Kutta [4][5][6], Galerkin's method of weighted residual [7,8], least squares method [9], and various collocation methods, including Haar wavelet [10,11], spectral [12], Chebychev [13][14][15], spectral element [16], Legendre [17], Adomian decomposition method [18,19], differential transform method [20][21][22], variational iteration method [23], homotopy analysis method [24], and hybrid methods [25][26][27]. Furthermore, in the quest to enhance the performance of fins, especially porous fins, different authors are investigating various thermal characteristics of porous fin including material, geometry, orientation, and composition are investigated to achieve heat transfer enhancement and augmentation.…”

This article presents the homotopy perturbation method (HPM) employed to investigate the effects of inclination on the thermal behavior of a porous fin heat sink. The study aims to review the thermal characterization of heat sink with the inclined porous fin of rectangular geometry. The study establishes that heat sink of an inclined porous fin shows a higher thermal performance compared to a heat sink of equal dimension with a vertical porous fin. In addition, the study also shows that the performance of inclined or tilted fin increases with decrease in length–thickness aspect ratio. The study further reveals that increase in the internal heat generation variable decreases the fin temperature gradient, which invariably decreases the heat transfer of the fin. The obtained results using HPM highlights the accuracy of the present method for the analysis of nonlinear heat transfer problems, as it agrees well with the established results of Runge–Kutta.

“…Based on the optical scattering and extinction properties of coal dust obtained from Mie scattering calculation, aimed at the transmission characteristics and aerosol optical depth (AOD) of dust particles, the numerical method of radiative transfer was applied [33][34][35][36][37][38]. Here, considering a gray medium condition, the one-dimensional radiative transfer equation (RTE) at the wavelength on the direction can be written as follows:…”

Respirable coal particle generated during underground mining is the main cause for gas-dust explosions and coal workers’ pneumoconiosis (CWP) which needs accurate monitoring especially on its concentration. Focusing on the coal dust pollution in the fully mechanized working face of Huangbaici coalmine, coal particle was sampled for further industrial analysis and FT-IR test to obtain its chemical composition and optical constant. Combined with the simulated spatial distribution of airborne dust, the spectral transmission characteristics of coal dust within wavelengths of 2.5 to 25 μm under different operating conditions were obtained. The simulation results show that the transmittance and aerosol optical depth (AOD) of coal dust are closely linked and obviously influenced by the variation of dust generation source (intensity of dust release, position of coal cutting, and the wetting of the coal seam) and airflow field (wind speed and direction of ventilation). Furthermore, an optical channel of 1260–1280 cm−1(7.937–7.813 μm) which is almost only sensitive to the variation of dust concentration but dull to the diameter change of coal dust was selected to establish the correlation of dust concentration and infrared transmittance. The fitting curve was then applied to retrieve the equivalent dust concentration based on optical information, and the comparison results demonstrate that the estimated pollution level is consistent with field measurement data in engineering practice.
