Project Overview We are developing a compact cylindrical chamber where fluid enters tangentially to create a strong vortex flow. The chamber currently produces rotational circulation, but we want to enhance the swirl strength and stability. The goal of this project is to design internal helical guide ribs (swirl-inducing surfaces) along the inner wall of the chamber to improve fluid circulation and increase angular momentum in the vortex core. We are seeking an engineer with experience in fluid mechanics and mechanical design to optimize the internal rib geometry. System Description Chamber type: cylindrical vortex chamber Internal diameter: ~150 mm Chamber height: ~200 mm Material: PVC or similar plastic Fluid: water Flow type: tangential inlet jets generating vortex circulation ...

I’m running a steady-state, two–phase condensation model for a single steam-carrying tube placed inside a rectangular duct through which the cooling medium flows. The goal is to quantify heat-transfer efficiency along the tube wall and map local condensation behaviour. All pre- and post-processing must be done in ANSYS Fluent – that is the environment my wider workflow depends on. I already have basic geometry and material data; what’s missing is a robust setup that captures phase change, solves for the temperature field on both sides of the tube, and outputs wall heat-flux, overall U-value, and condensate distribution with mesh-independent accuracy. Key points • Physics: two-phase (steam → liquid) condensation, steady-state, turbulent flow inside and ...

Scope of Work: Hydraulic Simulation of Water Spray Manifold System I require a hydraulic simulation of a water spray piping manifold installed inside a circular drum. The objective is to verify that each spray hole (nozzle) receives the required pressure and flow rate under the given operating conditions. The manifold distributes water through multiple small spray holes, and the simulation should confirm whether the design achieves uniform flow distribution and minimum pressure requirements at each spray point. Objectives: The simulation should determine: Pressure distribution along the spray manifold. Flow rate through each spray hole. Verification that each spray hole receives: Minimum pressure: 2.5 barg Minimum flow rate: 2.5 L/min Identification of any uneven distribution or pressu...
