  • NONLINEAR STRETCHING SHEET WITH HEAT SOURCE IN POROUS MEDIUM


Logmens William

Abstract: The presence of porous media in a boundary layer flow can significantly alter the field of flow and, as a consequence, affect the heat transfer rate at the surface.A Porous medium is generally modeled by using the classical Darcy formulation, which implies that the velocity of mean filter is proportional to the summation of the pressure gradient and the gravitational force.

  • General Relativity and Gravitational Waves: Exact Solutions of Einstein's Field Equations


Lingaraju

Abstract: This study delves into the exact solutions of Einstein's Field Equations (EFE) within the framework of General Relativity, focusing on the Schwarzschild, Kerr, and Friedmann-Lemaître-Robertson-Walker (FLRW) metrics. These solutions are pivotal in understanding a range of gravitational phenomena, from the properties of black holes to the dynamics of the expanding universe. The role of gravitational waves, as predicted by General Relativity, is explored, emphasizing their significance in testing the theory in the strong-field regime and providing insights into the universe's most extreme environments. The study also discusses the challenges inherent in solving the EFE, the importance of numerical relativity, and the future of gravitational wave astronomy, particularly through the development of nextgeneration detectors and the integration of multi-messenger observations. The findings underscore the continued relevance of Einstein's theory while highlighting the potential for new discoveries that could extend our understanding of gravity and the cosmos
