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 …
