شیخ عبدالحق محدث دہلوی کی علمی خدمات، منہج واسلوب اورعوامی مقبولیت و اثرات؛ ایک تحقیقی جائزہ A Research Review of the Work of Sheikh Abdul Haq Muḥaddith Dehlavi, It’s Style, Public Populaity & Influence

Sheikh Abdul Haq Muḥaddith Dehlavi is one of the prominent muhaddithin of the Subcontinent. He has played an unforgettable role in the leadership of the Ummah. His writings consist of God's benevolence, justice, and solving People’s problems so that they can look at their defects and focus on building their lives. He discussed topics related to the nation; do not follow useless philosophy and false interpretations which do not benefit a common man. Along with the reformed works, He has also left behind a large collection on technical topics. He wrote books on important and technical topics such as Tafseer, Tajweed, Hadith, Beliefs, Jurisprudence, Sufism, Ethics, Actions, Philosophy, History, Biography, etc. Sheikh Abdul Haq Muhaddith Dehlavi has priority in teaching and publishing the knowledge of Hadith. In the context of the publication of the knowledge of hadith, his two commentaries Mishkwat al-Masabih, Ishaat al-Lamaat and Lamaat al-Tanqeeh, has a special place. In the said article, an introduction and methodological study of the work done by Sheikh Abdul Haq will be presented.

Analytical Solutions for Boundary Layer Flows of Differential Type Fluids

The study of unsteady flow and heat transfer of non-Newtonian fluids over stretching surface is very important and serves a widespread variety of practical applications in industry. In this thesis, a theoretical study is undertaken into fluid flow and heat transfer due to stretching surface for the non-Newtonian second grade fluid. The second grade fluid considered in the current analysis is a subclass of differential type nonlinear fluid. Additionally, second grade liquid is capable to explore the features of normal stress impacts. More specifically, this thesis is concerned with study of the unsteady boundary layer flow and heat transfer characteristics for a second grade liquid over stretching surface and considered different problems of practical interest. The problems include, the forced convective heat transfer over stretching surface assuming different situations including nanolfuid, chemical processes and Cattaneo-Christov heat and mass flux relations. The transformed boundary layer equations are solved analytically by the homotopy analysis method. The analytical solutions have been computed for the velocity, temperature and concentration distributions. The effects of important physical parameters are presented graphically in order to visualize the impact of these parameters. The effects of non-dimensional parameters on the temperature, concentration and local Nusselt are elaborated through graphs and tables. The effect of non-dimensional parameters on the local Nusselt is discussed by using graphs. The obtained results reveal that the temperature profile diminishes for augmented values of the thermal relaxation parameter. In addition to this, it has come to the observation that the liquid temperature is higher for classical Fourier''s law when compared to non- Fourier''s law. It is estimated from the plots that the concentration of the second grade nanoliquid drops as the Brownian motion parameter increases while the reverse trend is detected for the thermophoresis parameter. Moreover, it is perceived from the results that the temperature of the second grade nanoliquid declines as unsteadiness parameter enhances.
