The use of renewabel energy continues to be encouraged so that power plants are reliable, simple, and can reach a remote area in Indonesia. One of the implementations that can be done in achieving this is the constructing of a Micro Hydro Power Plant. The use of Crossflow Water Turbine is a common turbine in Micro Hydro Power Plant due to the simple construction, low cost, and the easy fabrication process makes the crossflow water turbine quite promising to use. Therefore, it is necessary to design a crossflow water turbine and do a simulation process to understand the performance of crossflow water turbine with two-phase condition in low head with range 10 m – 30 m. Simulation process is done with computational fluid dynamics by using ANSYS Fluent Software in steady-state condition. The variation in this thesis are guide vane angle respect to x-axis, head, and admision angle. The result of design and simulation of crossflow water turbine shows that the maximum efficiency is 71,64%. It is reached with head 30 m. It occurs at 700 RPM rotation with a guide vane 10°. In variation of admision angle, the simulation is run in head 20 m with guide vane 0°. The maximum efficiency is 69.76% occurs at admision angle 90°.
