Experimental analysis and numerical modeling, using a one-dimensional spatial discretization model, based on thermohydraulic equations and solved by nodal network/electrical analogy, are presented to study the thermal and hydraulic behavior of the loop .

  The capillary pumped loop (CPL) is a passively pumped two-phase heat transport device that has demonstrated performance capabilities up to an order of magnitude greater than heat pipes, which are the current state-of-art. CPL technology has been developed to a near ready state for use as a thermal control device for advanced spacecraft systems. To further improve CPL . an applied pressure gradient. An experimental lab-scale installation is used for the validation of the theoretical analysis. The results showed that the proposed CPL modeling is able to describe very well the CPL performance.

Eng, 35 (), pp.   A numerical model to analyze the steady-state operational characteristics of loop heat pipes (LHPs) is presented. The mathematical model uses a new approach and is developed in a way that it can be easily extended to a transient model. The LHP components are discretized into control volumes.
