Reactive flows are flows that are chemically reactive, which finds its applications in many areas such as combustion(IC engine), propulsion devices (Rockets, jet engines etc.), detonations, fire and safety hazards, astrophysics etc. In addition to conservation of mass, momentum and energy, conservation of individual species (for example, mass fraction of methane in methane combustion) need to be derived, where the production/depletion rate of any species are obtained by simultaneously solving the equations of chemical kinetics.
Freyja rules over her heavenly afterlife field Flkvangr and there receives half of those that die in battle, whereas the other half go to the god Odin's hall, Valhalla. Within Flkvangr is her hall, Sessrmnir. Freyja assists other deities by allowing them to use her feathered cloak, is invoked in matters of fertility and love, and is frequently sought after by powerful jtnar who wish to make her their wife. Freyja's husband, the god r, is frequently absent. She cries tears of red gold for him, and searches for him under assumed names. Freyja has numerous names, including Gefn, Hrn, Mardll, Sr, Valfreyja, and Vanads.
Freyja is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources; in the Prose Edda and Heimskringla, composed by Snorri Sturluson in the 13th century; in several Sagas of Icelanders; in the short story Srla ttr; in the poetry of skalds; and into the modern age in Scandinavian folklore.
Scholars have debated whether Freyja and the goddess Frigg ultimately stem from a single goddess common among the Germanic peoples; connected her connection to the valkyries, female battlefield choosers of the slain; and analyzed her relation to other goddesses and figures in Germanic mythology, including the thrice-burnt and thrice-reborn Gullveig/Heir, the goddesses Gefjon, Skai, orgerr Hlgabrr and Irpa, Mengl, and the 1st century CE "Isis" of the Suebi. Freyja's name appears in numerous place names in Scandinavia, with a high concentration in southern Sweden. Various plants in Scandinavia once bore her name, but it was replaced with the name of the Virgin Mary during the process of Christianization. Rural Scandinavians continued to acknowledge Freyja as a supernatural figure into the 19th century, and Freyja has inspired various works of art.
