generate_frm_MB: Generate data for flow regime map (frm_MB)

In sshunsuke/MukherjeeBrill: Mukherjee & Brill model for gas-liquid two-phase flow in a circular pipe

Description

Generate a matrix (class="frm_MB") for a flow regime map. Range of the map is specified by vector_vsG and vector_vsL.

Usage

generate_frm_MB(
  vector_vsG,
  vector_vsL,
  D,
  densityG,
  densityL,
  viscosityG,
  viscosityL,
  surfaceTension,
  angle
)

Arguments

vector_vsG	Vector of Superficial velocity of gas - m/s
vector_vsL	Vector of superficial velocity of liquid - m/s
D	Pipe diameter - m
densityG	Density of gas - kg/m3
densityL	Density of liquid - kg/m3
viscosityG	Visosity of gas - Pa-s
viscosityL	Visosity of liquid - Pa-s
surfaceTension	Surface tension - N/m
angle	Pipe angle (0 is horizontal flow) - radian

Value

A matrix (class="frm_MB") including the information of flow regime (columns) at specified superfical velocities of gas and liquid.

• vsG: Superficial velocity of gas

• vsL: Superficial velocity of liquid

• fr: Flow regime (1: Stratified, 2: Annular, 3: Slug, and 4: Bubbly)

• NGv, NLv, NL, NGvSM, NGvBS, NLvBS_up, NLvST: Internal properties used in the prediction of flow regime
