The Himalayan cryosphere:A critical assessment and evaluation of glacial melt fraction in the Bhagirathi basin

引用

Geoscience Frontiers 2017年第1期8卷 107-115页

作者： Abul amir khan Naresh Chandra Pant Anindaya Sarkar S.K.Tandon Meloth Thamban Mahalinganathan K Department of Geology University of DelhiNew Delhi 11007India Department of Geology and Geophysics Indian Institute of TechnologyWest Bengal 721302India Department of Earth Science Indian Institute of TechnologyKanpurUttar Pradesh 208016India Department of Cryosphere Science National Centre for An tarctic and Ocean Research(NCAOR)Ministry of Earth SciencesGovernment of IndiaHeadland SadaVasco-da-GamaGoa 403804India

The cryosphere constitutes an important subset of the hydrosphere. The Himalayan cryosphere is a significant contributor to the hydrological budget of a large river system such as the Ganges. Basic data on the cryosphere in the Himalaya is inadequate and also has large uncertainties. The data on glacial melt component in the Himalayan rivers of India also shows high variability. The Gangotri glacier which constitutes nearly a fifth of the glacierized area of the Bhagirathi basin represents one of the fastest receding, large valley glaciers in the region which has been surveyed and monitored for over sixty years. The availability of measurement over a long period and relatively small glacier-fed basin for the Bha- girathi river provides suitable constraints for the measurement of the glacial melt fraction in a Himalayan river. Pre- and post-monsoon samples reveal a decreasing trend of depletion of 0180 in the river water from glacier snout （Gaumukh） to the confluence of the Bhagiratbi river with the Alaknanda river near Devprayag. Calculations of existing glacial melt fraction （-30% at Rishikesh） are not consistent with the reported glacial thinning rates. It is contended that the choice of unsuitable end-members in the three component mixing model causes the overestimation of glacial melt component in the river discharge. Careful selection of end members provides results （-11% at Devprayag） that are consistent with the expected thinning rates.

Some Exact Solutions of Generalized Jeffrey Fluid Using N-Transform

引用

American Journal of Computational Mathematics 2017年第4期7卷 402-412页

作者： amir khan Gul Zaman Saeed Ahmad M. Ikhlaq Chohan Department of Mathematics and Statistics University of Swat Swat Pakistan Department of Mathematics University of Malakand Lower Dir Pakistan Department of Business Administration and Accounting Buraimi University College Al-Buraimi Oman

In this paper, we presents some new exact solutions corresponding to three unsteady flow problems of a generalized Jeffrey fluid produced by a flat plate between two side walls perpendicular to the plate. The fractional calculus approach is used in the governing equations. The exact solutions are established by means of the Fourier sine transform and N-transform. The series solutions of velocity field and associated shear stress in terms of Fox H-function, satisfying all imposed initial and boundary conditions, have been obtained. The similar solutions for ordinary Jeffrey fluid, performing the same motion, appear as limiting case of the solutions are also obtained. Also, the obtained results are analyzed graphically through various pertinent parameters.

The Oscillatory Motion of Oldroyd-B Fluid by Incorporating Some of the Mechanical Factors

引用

Journal of Applied Mathematics and Physics 2017年第12期5卷 2402-2410页

作者： amir khan Gul Zaman Yongjin Li Saeed Ahmad Altaf Hussain Department of Mathematics and Statistics University of Swat Khyber Pakhtunkhwa Pakistan Department of Mathematics University of Malakand Chakdara Dir (Lower) Khyber Pakhtunkhwa Pakistan Department of Mathematics Sun Yat-sen University Guangzhou China

The aim of this paper is to present a numerical study of oscillatory motion of Oldroyd-B fluid in a uniform magnetic field through a small circular pipe. First, we derive the orientation stress tensor by considering the Brownian force. Then, the orientation stress tensor is incorporated by taking Hookean dumbbells on Brownian configuration fields in the Oldroyd-B model. The Oldroyd-B model is then reformulated coupled with the momentum equation and the total stress tensor. Finally, we analyze the orientation stress tensor in the pipe by the numerical simulations of the model and showed that the effect of orientation stress tensor is considerable although the Brownian force is sufficiently small.
