Numerical investigation of hydrodynamics and thermal performance of a specially configured heat pipe for high-temperature thermal energy storage systems

Experimental investigation on thermal performance of phase change material coupled with closed-loop oscillating heat pipe (PCM/CLOHP) used in thermal management

“…One is increasing the thermal conductivity of PCM by adding high thermal conductive particles or fillers to fabricate composite PCM, such as paraffin wax/expanded graphite (paraffin wax/EG) [5,6], paraffin wax/metal foams [7][8][9], and paraffin wax/nano-materials [10,11]. The other one is placing high thermal conductivity inserts into PCM through structure design, such as aluminum fins [12,13], capillary driven heat pipe, gravity assisted heat pipe (GHP) [14][15][16][17][18][19], and others.…”

Heat pipe heat exchangers and heat sinks: Opportunities, challenges, applications, analysis, and state of the art

“…In the study, integration of the PCM with the HP improved receiver performance, reduced time-wise temperature variations of the fluid flow, and decreased the weight of the receiver. Mahdavi et al [73] analyzed the performance of a particular heat pipe integrated with Dish-Stirling systems. In the proposed design, a primary HP transferred the absorbed solar thermal energy to the engine heater head vapor chamber to which an array of secondary HPs was connected to transfer the excess solar thermal energy into the PCM for later use.…”

Three-dimensional simulation of high temperature latent heat thermal energy storage system assisted by finned heat pipes

“…In the present study, heat pipe is considered as an element with high effective thermal conductivity k hp . The operation of heat pipe was studied in a parallel work by Mahdavi et al [53,54] …”
