Heat Transfer Assessment in a Vaporizing Liquid Microthruster undergoing Dual Heating Control

In the present work, a new VLM design is proposed to ensure a safer and more efficient heat transfer of high-energy from solid walls to fluid. In this regard, an innovative approach is introduced to separate the boiling and overheating processes by implementing two distinct heating chambers. A quasi-1D steady-state numerical model has been developed to solve the flow into the VLM at constant heat flux boundary conditions, allowing for a preliminary performance assessment of dual heating control. Thus, in-depth insights derived from both the experimental assessment and numerical analysis are comprehensively discussed and presented, highlighting their relevance and significance in understanding the heat transfer process.the most relevant insights are discussed together with the numerical analysis.
