“…Solar dryers are showing significant presence in the global market due to their fossil fuel free operating requirements in food preservation. It is also observed from the literature that both the RSM and CFD have been collectively used in the design and optimization of various thermal systems such as a direct contact membrane distillation (Choi et al, 2022), divergent-chimney solar power plant (Adibimanesh et al, 2021), double pipe heat exchanger with cut twisted tapes (Kola et al, 2021), solar air heater (SAH) with inclined fin (Qader et al, 2019), direct contact membrane EC 41,4 distillation (DCMD) desalination system under counter-current flow (Zare and Kargari, 2022), grooved micromixers with obstructions (Rahmannezhad and Mirbozorgi, 2019), solar chimney power plant (Sundararaj et al, 2022), wavy lobed heat exchanger tube (Hadibafekr et al, 2023) and ionizer nozzle structure (Zhang et al, 2024). Kumar and Bansal (2013) optimized the photocatalytic degradation in an annular reactor by using a combination of CFD and RSM techniques.…”

PurposeFood loss and wastage is an issue of global concern and the household sector is one of the biggest contributors to this. Solar drying has been explored by many eminent researchers as a solution to this problem but there have been concerns about the lack in designs, higher cost, lower performance, and consumer acceptability. The present research aims to design a small-scale domestic solar dryer by using computer software.Design/methodology/approachResponse surface methodology (RSM) and computational fluid dynamics (CFD) are used to design the domestic solar dryer. Initially, design variables (inlet and outlet vent height) are identified and a design of experiments has been created using RSM for set of experimental runs. The experimental runs suggested by RSM were carried out using CFD simulation in COMSOL Multiphysics software and the results were used for optimization of response variables (outlet velocity and drying chamber temperature) in RSM.FindingsOutlet vent height was found to be most significantly affecting parameter to both the responses. The optimum values of inlet and outlet vent heights were 0.5 and 2.5 cm, respectively with the overall desirability of 0.728. The model accuracy was tested by conducting a confirmation test as post processing in design expert software.Originality/valueDesigning a solar dryer is a complex, costly and time consuming process, this study presents an easy, economic and fast method to design a new solar dryer. It would help researchers to design and develop new domestic as well as large size industrial solar dryer.
