Package detail

1. Installation

J**aSali is part of the ASALI project and it is a **JavaScript library to estimate thermodynamic and transport properties of gas mixtures.
Its npm package can be installed as follow:

npm i jasali

2. Examples - JaSali is based on International System of Units

J**aSali allows the estimation of thermodynamic and trasport properties of **pure gas species and gas mixtures, as shown in the following examples.

2.1 Pure gas specie: O₂

import {
  GasState,
  GasSpecie
} from "jasali"

//Generate gas state object
let state = GasState({
  temperature: 393.15,
  pressure: 4e05
})

//Generate specie object
let specie = GasSpecie({
  name: "O2",
  gasState: state
})

//Extract properties from the specie object
let name = specie.getName()
let molecularWeight = specie.getMolecularWeight()
let viscosity = specie.getViscosity()

2.2 Gas mixture: AIR

import {
  GasState,
  GasMixture
} from "jasali"

//Generate gas state object
let state = GasState({
  temperature: 298.15,
  pressure: 101325
})

//Generate mixture object
let mixture = GasMixture({
  mixtureComposition: {
    "O2": 0.21,
    "N2": 0.78,
    "AR": 0.01
  },
  gasState: state,
  compositionType: "mole"
})

//Extract properties from the mixture object
let density = mixture.getDensity()
let molecularWeight = mixture.getMolecularWeight()
let viscosity = mixture.getViscosity()

2.3 Gas mixture: Chemical equilibrium at constant temperature and pressure

import {
  GasState,
  GasMixture
} from "jasali"

//Generate gas state object
let state = GasState({
  temperature: 3000,
  pressure: 4e05
})

//Generate mixture object
let mixture = GasMixture({
  mixtureComposition: {
    "CO": 0.1,
    "CO2": 0.2,
    "O2": 0.7
  },
  gasState: state,
  compositionType: "mole"
})

//Extract chemical equilibrium composition
let x = mixture.calculateChemicalEquilibriumTP()

2.4 HTML frontend

This examples shows how to use J**aS**ali from a pure frontend HTML file:

<script type="text/javascript" src="./jasali.js"></script>

<script>
function gasMixtureProperties()
{
  //Generate gas state object
  let state = jasali.GasState({
    temperature: 3000,
    pressure: 4e05
  })

  //Generate mixture object
  let mixture = jasali.GasMixture({
    mixtureComposition: {
      "CO": 0.1,
      "CO2": 0.2,
      "O2": 0.7
    },
    gasState: state,
    compositionType: "mole"
  })

  //Extract properties from the mixture object
  let density = mixture.getDensity()
}
</script>
