我正在做一个关于层流预混合火焰在不同复杂程度上的数值分析的项目。我非常需要帮助,因为我是Python和Cantera的新手。我有以下疑问:
程序如下:
"""
Adiabatic flame temperature and equilibrium composition for a fuel/air mixture
as a function of equivalence ratio, including formation of solid carbon.
"""
import cantera as ct
import numpy as np
import sys
import csv
##############################################################################
# Edit these parameters to change the initial temperature, the pressure, and
# the phases in the mixture.
T = 300.0
P = 101325.0
# phases
gas = ct.Solution('gri30.xml')
carbon = ct.Solution('graphite.xml')
# the phases that will be included in the calculation, and their initial moles
mix_phases = [(gas, 1.0), (carbon, 0.0)]
# gaseous fuel species
fuel_species = 'CH4'
# equivalence ratio range
npoints = 50
phi = np.linspace(0.3, 3.5, npoints)
##############################################################################
mix = ct.Mixture(mix_phases)
# create some arrays to hold the data
tad = np.zeros(npoints)
xeq = np.zeros((mix.n_species,npoints))
for i in range(npoints):
# set the gas state
gas.set_equivalence_ratio(phi[i], fuel_species, 'O2:1.0, N2:3.76')
# create a mixture of 1 mole of gas, and 0 moles of solid carbon.
mix = ct.Mixture(mix_phases)
mix.T = T
mix.P = P
# equilibrate the mixture adiabatically at constant P
mix.equilibrate('HP', solver='gibbs', max_steps=1000)
tad[i] = mix.T
print('At phi = {0:12.4g}, Tad = {1:12.4g}'.format(phi[i], tad[i]))
xeq[:,i] = mix.species_moles
# write output CSV file for importing into Excel
csv_file = 'adiabatic.csv'
with open(csv_file, 'w') as outfile:
writer = csv.writer(outfile)
writer.writerow(['phi','T (K)'] + mix.species_names)
for i in range(npoints):
writer.writerow([phi[i], tad[i]] + list(xeq[:,i]))
print('Output written to {0}'.format(csv_file))
if '--plot' in sys.argv:
import matplotlib.pyplot as plt
plt.plot(phi, tad)
plt.xlabel('Equivalence ratio')
plt.ylabel('Adiabatic flame temperature [K]')
plt.show()

请问我具体的问题,因为即使我不知道具体要问什么。但我知道我想做什么。你知道吗
这是一个有趣的问题。你知道吗
原则上不应该太难。假设您已给出入口燃料成分、当量比和绝热火焰温度,步骤如下:
