The c.mbi.ed effec.s of thermal and mass c.nvec.i.n of vi.c.us i.c.m- pressi.le and i.mi.c.ble flui.s through a verti.0}l wavy wall and a smooth flat wall are analyzed. The di.ensi.nless governi.g equati.ns are perturbed i.to a mean part （the zeroth-order） and a perturbed part （the fi.st-order）. The fi.st-order quanti.i.s are ob- tai.ed by the perturbati.n seri.s expansi.n for short wavelength, i. whi.0} the terms of the exponenti.l order ari.e. The analyti.0}l expressi.ns for the zeroth-order, the fi.st-order, and the total soluti.ns are obtai.ed. The numeri.0}l c.mputati.ns are presented graph- i.0}lly to show the sali.nt features of the flui. flow and the heat transfer c.arac.eri.ti.0}. Separate soluti.ns are matc.ed at the i.terfac. by usi.g sui.able matc.i.g c.ndi.i.ns. The shear stress and the Nusselt number are also analyzed for vari.ti.ns of the governi.g parameters. i. i. observed that the Grashof number, the vi.c.si.y rati., the wi.th rati., and the c.nduc.i.i.y rati. promote the veloc.ty parallel to the flow di.ec.i.n.
