t.e st.bilit. analysis of a finit. St.kes layer is of pract.cal import.nce in flow cont.ol. In t.e present.work, t.e inst.nt.neous st.bilit. of a finit. St.kes layer wit. layer int.ract.ons is st.died via a linear st.bilit. analysis of t.e frozen phases of t.e base flow. t.e oscillat.ons of t.o plat.s can have different.velocit. amplit.des, init.al phases, and frequencies. t.e effect. of t.e St.kes-layer int.ract.ons on t.e st.bilit. when t.o plat.s oscillat. synchronously are analyzed. t.e growt. rat.s of t.o most.unst.ble modes when δ t.equal, and δ = δ*/h*, where δ*and h*are t.e St.kes-layer t.ickness and t.e half height.of t.e channel, respect.vely. However, t.eir vort.cit.es are different. t.e vort.cit. of t.e most.unst.ble mode is symmet.ic, while t.e ot.er is asymmet.ic. t.e St.kes-layer int.ract.ons have a dest.bilizing effect.on t.e most.unst.ble mode when δ t.bilizing effect.when δ > 0.68. However, t.e int.ract.ons always have a st.bilizing effect.on t.e ot.er unst.ble mode. It.is explained t.at.one of t.e t.o unst.ble modes has much higher dissipat.on t.an t.e ot.er one when t.e St.kes-layer int.ract.ons are st.ong. We also find t.at.t.e st.bilit. of t.e St.kes layer is closely relat.d t. t.e inflect.onal point. of t.e base-flow velocit. profile. t.e effect. of inconsist.nt.velocit.-amplit.de, init.al phase, and frequency of t.e oscillat.ons on t.e st.bilit. are analyzed. t.e energy of t.e most.unst.ble eigenvect.r is mainly dist.ibut.d near t.e plat. of higher velocit. amplit.de or higher oscillat.on frequency. t.e effect. of t.e init.al phase difference are complicat.d because t.e base-flow velocit. is ext.emely sensit.ve t. t.e init.al phase.
