Lenoir Cycle - Constant Volume Heat Addition (1-2)

Constant Volume Heat Addition (1-2)

In the ideal gas version of the traditional Lenoir cycle, the first stage (1-2) involves the addition of heat in a constant volume manner. This results in the following for the first law of thermodynamics:

There is no work during the process because the volume is held constant:

and from the definition of constant volume specific heats for an ideal gas:

Where R is the ideal gas constant and γ is the ratio of specific heats (approximately 287 J/(kg·K) and 1.4 for air respectively). The pressure after the heat addition can be calculated from the ideal gas law:

Famous quotes containing the words constant, volume, heat and/or addition:

    Justice is the set and constant purpose which gives every man his due.
    Marcus Tullius Cicero (106–43 B.C.)

    To be thoroughly conversant with a Man’s heart, is to take our final lesson in the iron-clasped volume of despair.
    Edgar Allan Poe (1809–1845)

    Two wooden tubs of blue hydrangeas stand at the foot of the stone steps.
    The sky is a blue gum streaked with rose. The trees are black.
    The grackles crack their throats of bone in the smooth air.
    Moisture and heat have swollen the garden into a slum of bloom.
    Pardie! Summer is like a fat beast, sleepy in mildew....
    Wallace Stevens (1879–1955)

    As easy mayst thou fall
    A drop of water in the breaking gulf,
    And take unmingled thence that drop again,
    Without addition or diminishing,
    As take from me thyself and not me too.
