This　paper　investigates　the　viscosity　vanishing　limit　and　the　existence　and　uniqueness　of　the　global　strong　solution　on　the　three-dimensional　incompressible　Navier-Stokes　equations　without　swirl　in　spherical　coordinates.　We　establish　the　global　existence　and　uniqueness　of　the　smooth　solution　to　the　Cauchy　problem　for　the　three-dimensional　incompressible　Navier-Stokes　equations　for　the　any　smooth　large　initial　data　without　swirl　in　the　sense　of　spherical　coordinates.　Also,　by　performing　the　viscosity　vanishing　limit　for　the　global　strong　solution　in　time　to　the　three-dimensional　incompressible　Navier-Stokes　equations,　we　prove　that　there　exists　the　unique　and　global　strong　solution　to　the　Cauchy　problem　for　the　three-dimensional　incompressible　Euler　equation　without　swirl　in　spherical　coordinates　with　large　initial　data.　(C)　2019　Elsevier　Ltd.　All　rights　reserved.
