Heat transport investigation of engine oil based rotating nanomaterial liquid flow in the existence of partial slip effect

In this study, rotational nano liquid movement above a linearly stretching surface has been formulated. A two-phase model is used for this analysis. Base fluid engine oil and two distinct types of nanoparticles are used as nanoparticles, i.e. copper and aluminum oxide (Cu & Al2O3). This study is aimed to describe the changed possessions on velocity and temperature for rotational nanofluid flow above a linear enlarging surface in the existence of the slip effect. The leading structure of PDEs is converted into ODEs with a similarity transformation. Numerical findings are gained utilizing a sophisticated numerical approach. For both nanofluids, the results for rotational flow and heat transmission characteristics are emphasized with the help of graphs. At the linear extending surface, the influence of physical concentrations like heat flow rates and skin friction coefficients is investigated and visually clarified. Cunanoparticles proved to be better heat carriers than Al2O3 nanoparticles

Heat Transfer Analysis of Nanostructured Material Flow over an Exponentially Stretching Surface: A Comparative Study

The objective of the present research is to obtain enhanced heat and reduce skin friction rates. Different nanofluids are employed over an exponentially stretching surface to analyze the heat transfer coefficients. The mathematical model for the problem has been derived with the help of the Rivilin–Erickson tensor and an appropriate boundary layer approximation theory. The current problem has been tackled with the help of the boundary value problem algorithm in Matlab. The convergence criterion, or tolerance for this particular problem, is set at 10−6. The outcomes are obtained to demonstrate the characteristics of different parameters, such as the temperature exponent, volume fraction, and stretching ratio parameter graphically. Silver-water nanofluid proved to have a high-temperature transfer rate when compared with zinc-water and copper-water nanofluid. Moreover, the outcomes of the study are validated by providing a comparison with already published work. The results of this study were found to be in complete agreement with those of Magyari and Keller and also with Lui for heat transfer. The novelty of this work is the comparative inspection of enhanced heat transfer rates and reduced drag and lift coefficients, particularly for three nanofluids, namely, zinc-water, copper-water, and silver-water, over an exponentially stretching. In general, this study suggests more frequent exploitation of all the examined nanofluids, especially Ag-water nanofluid. Moreover, specifically under the obtained outcomes in this research, the examined nanofluid, Ag-water, has great potential to be used in flat plate solar collectors. Ag-water can also be tested in natural convective flat plate solar collector systems under real solar effects

ELECTORAL PERFORMANCE OF PAKISTAN TEHREEK-I-INSAF IN ELECTIONS 2018: A STUDY OF DISTRICT KHUSHAB

Factionalism and electable is a trending factor in in the power politics of Punjab. The political elites of Punjab are majorly based in rural areas that also have influential background on the basis of their castes. The politics of Khushab is completely based on electable and caste system. This paper is an attempt to identify the major influential classes of district Khushab and trends of politics before and during elections 2018. The part played by PTI in this region and the influential youth wing changed the discourse of politics of district Khushab. The tactics, strategies and style for power politics is analyzed. This study is based on qualitative approach and as a case study of the politics Khushab during elections 2018. The study highlighted that the politics of PTI got momentum on several basis in the region, however, the winnings of the party in elections 2018 was the outcome of factionalism and electable
