1、安装Anaconda ;
2、打开Anaconda Prompt,输入 conda create -n test -c cantera cantera ipython matplotlib ,出现提时,输入 y (如果你不是第一次下载,只需要找到Anaconda下对应的Anaconda Prompt即可);
3、检查是否安上cantera,输入 activate test 按回车,输入 conda list ,查看是否有cantera(这一步本人以为可以省略);
4、打开Anaconda,把Applications on 换成test ,点击Spayder的install(是为了下载此种情况下的spyder,如果已经有了,即为launch状态,直接打开即可);
5、试运行代码(为他们公司所提供的代码);
import cantera as ct
import numpy as np
import matplotlib.pyplot as plt
gas = ct.Solution('gri30.yaml')
initial_state = 1200, 5 * ct.one_atm, 'CH4:0.35, O2:1.0, N2:3.76'
# Run a simulation with the full mechanism
gas.TPX = initial_state
r = ct.IdealGasConstPressureReactor(gas)
sim = ct.ReactorNet([r])
tt = []
TT = []
t = 0.0
# Rmax is the maximum relative reaction rate at any timestep
Rmax = np.zeros(gas.n_reactions)
while t < 0.02:
t = sim.step()
tt.append(1000 * t)
TT.append(r.T)
rnet = abs(gas.net_rates_of_progress)
rnet /= max(rnet)
Rmax = np.maximum(Rmax, rnet)
plt.plot(tt, TT, label='K=53, R=325', color='k', lw=3, zorder=100)
# Get the reaction objects, and sort them so the most active reactions are first
R = sorted(zip(Rmax, gas.reactions()), key=lambda x: -x[0])
# Test reduced mechanisms with different numbers of reactions
C = plt.cm.winter(np.linspace(0, 1, 5))
for i, N in enumerate([40, 50, 60, 70, 80]):
# Get the N most active reactions
reactions = [r[1] for r in R[:N]]
# find the species involved in these reactions. At a minimum, include all
# species in the reactant mixture
species_names = {'N2', 'CH4', 'O2'}
for reaction in reactions:
species_names.update(reaction.reactants)
species_names.update(reaction.products)
# Get the species objects
species = [gas.species(name) for name in species_names]
# create the new reduced mechanism
gas2 = ct.Solution(thermo='IdealGas', kinetics='GasKinetics',
species=species, reactions=reactions)
# Re-run the ignition problem with the reduced mechanism
gas2.TPX = initial_state
r = ct.IdealGasConstPressureReactor(gas2)
sim = ct.ReactorNet([r])
t = 0.0
tt = []
TT = []
while t < 0.02:
t = sim.step()
tt.append(1000 * t)
TT.append(r.T)
plt.plot(tt, TT, lw=2, color=C[i],
label='K={0}, R={1}'.format(gas2.n_species, N))
plt.xlabel('Time (ms)')
plt.ylabel('Temperature (K)')
plt.legend(loc='upper left')
plt.title('Reduced mechanism ignition delay times\n'
'K: number of species; R: number of reactions')
plt.xlim(0, 20)
plt.tight_layout()
plt.show()

2、beidou111 的 安装cantera并且运行一个官方示例,网址安装cantera并且运行一个官方示例_beidou111的博客-CSDN博客_cantera安装
特别致谢。
3、代码是官网的,网址mechanism_reduction.py | Cantera
4、如果操作时仍有失败的情况,欢迎留言。)
