We have obtained the values of Takens-Bogdanov bifurcation points and codimension-two bifurcation points by plotting graphs of neutral curves corresponding to stationary and oscillatory  convection for different values of physical parameters. We have studied Nusselt number from  Landau-Ginzburg equation at the onset of stationary convection for the steady case. We have also derived a nonlinear two dimensional Landau-Ginzburg equation near the onset of stationary convection at a supercritical pitchfork bifurcation and nonlinear  one-dimensional coupled Landau-Gingburg type equations near the onset of oscillatory convection at a supercritical Hopf bifurcation. We have discussed the stability regions of standing and travelling waves. We have also discussed the occurrence of  secondary instabilities such as Eckhaus, Zigzag and Benjamin-Feir instabilities.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659599583\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659599583","offer_id":39467484479581,"sku":"9783659599583","price":45.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c16705dd-c303-49bd-a7c4-692b7f4aceeb.jpg?v=1773381521","url":"https:\/\/shop.autorenwelt.de\/products\/convection-in-earths-outer-core-due-to-thermal-compositional-buoyancy-von-benerji-babu-avula","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
