We study the dynamics of electroweak bubbles in the scenario of a strongfirst order inverse electroweak phase transition at the TeV scale involving theglobal structure of the nonlinear sigma field in the littlest Higgs model withT parity. Employing the one-loop order finite temperature effective potential,we find that the pressure in the symmetric phase i.e., inside the bubble isalways greater than that in the asymmetric phase i.e., outside the bubble, sothat the bubbles are expanding. By calculating the fluid velocities in the twophases we arrive at the condition of a supersonic deflagrated motion of thebubble walls. We then discuss the generation of gravitational waves from thecollisions of such bubbles as well as from the turbulence of the plasma.
