Looking at the volute and flow system, RED will have 120 channels each one sized to be 0.035 " by 0.03 " for coolant must maintain equal pressure and mass flow rates. To do this, I designed a volute system that can evenly distribute the flow of coolant into the channels by using a volute, spoke manifold system.
How It Works
 

Volute being prepared for CFD after new CAD was finished.
A volute is machined into the interior of the engine Jacket with  40 spokes of equal diameter coming out and into a manifold that sits above the channels. Three O-rings are placed at points where fluid flow could exit the system. All of the channels move towards a manifold within the injector where it can then distribute to the swirl and film cooling holes. 
After seeing presentations from other student teams, a concern around each cooling channel buckling inward became a concern, so I made a calculator to estimate the pressure placed on the channel liner to see how likely is is to too buckle and what can be done to ensure this doesn't happen. This data was compared with changes in thermal stress to ensure there wouldn't be extreme strain placed on the liner and convective heat transfer would still be effective.
