Assignment 11

single cyl DI add case 2 with discretization length 0.1 mm for intake runner and compare with default case 1

• • Parameters-Torque, BSFC, max cylinder pressure
  • simulation time

case setup:

Results:

parameters	for 40mm discretisatio length	for 0.1mm discretisatio length
time	9.3	1043
max cylinder pressure	117.1	115.21
bsfc	238.2	238.9
torque	96.2	95.9

if the discretisation length become smaller the accuracy become higher.

“Building intake manifold from STL model”

the 3d model had been edited by using GEM3d .

the 3d model was completely splited into many parts after the complicated shapes were edited as standard shape.

the model was imported and the pipe bends were splited and then converted as pipe .

the planum was after converte as flow split component all components were join togather by using flow connection tool.
