The Power-law model is considered to explore the non-Newtonian property of blood. Two-point Gauss quadrature formula is applied to obtain the numerical expressions of dimensionless flow resistance, skin-friction and flow rate. The variation of dimensionless flow resistance, skinfriction and flow rate with degree of stenosis, axial distance and power-law index is shown graphically. Moreover, the power-law index is adjusted to explore the non-Newtonian characteristics of blood. The importance of the present work has been carried out by comparing the results with other theories both numerically and graphically. It has been found that resistance to flow becomes maximum with total blockage of artery for different shape of stenosis.","PeriodicalId":36607,"journal":{"name":"Journal of Mathematical and Computational Science","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74404462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a three dimensional solid oxide fuel cell in planar configuration, with hydrogen fuel and air as oxidant, has been modeled using COMSOL Multiphysics software. The gas flow in the gas channels is modeled by Navier Stokes equations while that through the electrodes is studied by applying the Brinkman equations. The model is simulated for the variation in the sizes of the gas diffusion channel including length, height and width of the channel. The polarization and power characteristics of the cell are plotted and studied over the variations. The cell performance is evaluated considering counter-flow and co-flow of the gases in the channels, separately. A clear impact of the change in the sizes of the channel is observed on the performance of the cell. A comparison of the counter-flow and coflow patterns has also been made. 2 SAHIL BANSAL, ANAND K.

Abstract. We would like to state well-known Ostrowski inequality via h−convex by using the Fuzzy Reimann integrals. In addition, we establish some Fuzzy Ostrowski type inequalities for the class of functions whose derivatives in absolute values at certain powers are h−convex by Hölder’s and power mean inequalities. This class of h−convex function, which is the generalization of many important classes including class of Godunova-Levin s−convex, s−convex in the 2nd kind and hence contains convex functions. It also contains class of P−convex and class of Godunova-Levin. In this way we also capture the results with respect to convexity of functions.","PeriodicalId":36607,"journal":{"name":"Journal of Mathematical and Computational Science","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81728887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The unknown function in the equation is first expressed as a product of an appropriate weight function and a truncated weighted series of Chebyshev polynomial of the first kind. Some properties of Chebyshev polynomials are then used to reduce the equation to a system of linear equations. On solving the linear system, the numerical solution of the Cauchy singular integral equation is obtained at Chebyshev nodes, after which barycentric interpolation is used to obtain the numerical solution at non-Chebyshev nodes.
