GTEngine
Math models of gas turbine engine and its parts made with ruby language
Usage
Add gem to your gemfile
gem 'gtengine'
and run
bundle
Simple
For simple parts calculation:
gas = Gtengine::Gas.new(300, 101325)
k = Gtengine::Simple::Compressor.new(gas, 4.5)
b = Gtengine::Simple::Burner.new(k.output, 1500)
t = Gtengine::Simple::Turbine.new(b, k.l_k)
k.info; b.info; t.info
To play with cycle (compressor -> burner -> turbine)
require_relative 'lib/gtengine'
gas = Gtengine::Gas.new(300, 101325)
c = Gtengine::Simple::Cycle.new(gas, 20, 1500.0)
c.compressor.info; c.burner.info; c.turbine.info; c.info
To play with pi_k optimization
require_relative 'lib/gtengine'
gas = Gtengine::Gas.new(300, 101325)
opt = Gtengine::Simple::PikOptimizer.new(gas, 3, 40, 1500, 1)
opt.info
Cycle research with T_g and pik
require_relative 'lib/gtengine'
gas = Gtengine::Gas.new(300, 101325)
res = [900, 1000, 1100, 1200, 1300, 1400, 1500].inject({}) do |memo, t_g|
opt = Gtengine::Simple::PikOptimizer.new(gas, 3, 40, t_g, 1)
memo.merge(t_g.to_s => opt.optimal.pi_k)
end
puts res
Compressor
Compressor initializer gets 3 arguments as input:
Gtengine::Simple::Compressor.new(gas, pi_k, options)
where:
- gas - is gas state, as
Gtengine::Gasclass - pi_k - is pi_k
- options - is a hash of options, defaults are:
DEFAULTS = {
kpd: 0.85
}
Burner
Burner initializer gets 3 arguments as input:
Gtengine::Simple::Burner.new(gas, t_g, options)
where:
- gas - is gas state, as
Gtengine::Gasclass - t_g - is t_g
- options - is a hash of options, defaults are:
DEFAULTS = {
t_0: 288.3,
q_n: 43000000.0,
eta_g: 0.985,
l_0: 14.7
}
Turbine
Turbine initializer gets 3 arguments as input:
Gtengine::Simple::Turbine.new(burner, l_k, options)
where:
- burner - is burner, as
Gtengine::Simple::Burnerclass - l_k - is l_k
- options - is a hash of options, defaults are:
DEFAULTS = {
eta: 0.9,
eta_m: 0.985,
g_ohl: 0.001,
kpd: 0.9
}
