Ensuring the Protection of Flood Embankments: A Vital Necessity
Abstract: In the face of flooding events, safeguarding flood embankments becomes imperative. These situationsoften involve rivers with significant water depth and velocity, leading to the exertion of considerablethrust due to the presence of standing water and the flow's speed. These embankments are typicallyconstructed using compacted non-cohesive soil. To prevent erosion of the embankment, it is crucial thatthe thrust of water applied to it remains within the bearing capacity limits of the …

Design and CFD Analysis with Experimental Testing of Exhaust Manifold
Abstract: The exhaust manifold undergoes back pressure problems. If the design of the manifold consists of sharp edges or bends which will tend to create turbulence and increase in pressure. Due to increase in turbulence it can cause an increase in back pressure. As the back pressure increases it tends to improper scavenging of the exhaust gases. So the improper scavenging of the gases leads to improper burning of fuel which …
