Numerical Analysis of a Hydrodynamic Herringbone Grooved Journal Bearing

Algorithm 1

Algorithm proposed by Hajam and Bonneau [12].

	Input data
	Initialization
	Do until stability of area (breakdown and reforming domain boundary)
	Compute E (modified Reynolds equation)
	Do For each node
	If node is full
	If E < 0
	the node is set to the inactive state
	else
	the node still active
	end if
	else
	If E ≥ 0
	the node is set to the active state
	else
	the node still inactive
	end if
	end if
	End
	End
	Do For each x-coordinate (circumferential direction)
	Do For each z-coordinate (axial direction)
	Determine Zp = the nearest z-coordinate with p = Patm
	End
	Sealing length = Max (Zp)
	End
	Write pressure, sealing length, …
	End algorithm
